When to Worry About Heart Palpitations

By Stephen T. Sinatra, M.D., F.A.C.C., F.A.C.N., C.N.S., C.B.T.

At some point in our lives, most all of us will experience heart fluttering, racing, skipping, or another kind of irregular heartbeat. It’s incredibly common. But because it affects the heart, it also can be incredibly frightening.

Myself, I’ve had a couple episodes with PVCs (premature ventricular contractions). Let me tell you, they get your attention!

I saw hundreds of patients over the years who were concerned about heart palpitations. In many of those cases, the irregular beats turned out to be 100 percent benign—nothing to worry about. But I also saw a lot of people whose palpitations were their bodies’ way of telling them that their heart needed help.

What Is a Heart Palpitation?

Heart Palpitation Risk Depends on the Cause

The most important part of evaluating heart palpitations is determining what’s causing them. I always liked to start by asking patients some questions about their lifestyle:

  • Were they eating too much sugar, caffeine, or other foods that cause palpitations?
  • How much stress and anxiety did they have in their lives?
  • Were they feeling emotions that they didn’t feel they could talk about?
  • Did their palpitations tend to happen at a certain time? (A heart racing at night was common.)
  • What medications are they on?

The answers to these questions helped me understand whether external issues could be causing the skips, jumps, or flutters. If, after I finished my work-up, all of a patient’s risk factors fell into this bucket, I didn’t worry too much about their heart palpitations. Instead, I’d start working with them on adopting new habits that could address the problem.

What concerned me was when I found internal issues with the heart that could be causing someone’s palpitations, or that could become dangerous if it was combined with palpitations. Here are six specific examples of when it’s right to worry…

6 Causes of Heart Palpitations that Are Reason for Worry

Diastolic Dysfunction

In people who have diastolic dysfunction (DD), there are problems with the structure and function of the heart—a major risk factor when evaluating whether palpitations are dangerous. With a normal heart, I never worried too much about irregular beats. But when a patient’s heart was compromised in some way, it was a different story.

With diastolic dysfunction, the ventricles (the lower chambers of the heart) lose their elasticity and can’t fully relax and fill with blood like they’re supposed to. This causes the heart to beat faster and less efficiently.

Sometimes we’ll see palpitations as a symptom of DD, but I worry more about how they can affect the disease’s progression (it can lead to full-blown heart failure) and their potential to disrupt an already struggling heart.

A major issue with DD is all the extra wear and tear it puts on the heart. When you throw in irregular beats, it adds to that already heavy workload. Even more problematic, though, is that irregular beats have the potential to disrupt electrical signals and lead to life-threatening arrhythmias.

If you’re having heart palpitations or it feels like your heart’s racing, diastolic dysfunction is something you’re going to want to have your doctor assess—doubly so if you’re a woman. DD is much more likely to occur in women than in men.

High Blood Pressure

High blood pressure and heart palpitations are a bad mix for one of the same reasons that diastolic dysfunction is—the workload they put on the heart. High blood pressure is a major cause of DD, and heart palpitations can raise risk even more.

If you have both high blood pressure and palpitations, you must keep your blood pressure in check. Make sure you’re eating an anti-inflammatory diet,  managing your stress, and, if necessary, taking prescription medication; I also recommend taking supplements that can help lower blood pressure. (Check out my full blood pressure–lowering plan.)

Mitral Valve Prolapse

Another cause of heart palpitations that can be worrisome is mitral valve prolapse, or MVP.

If you have MVP, it means the valve separating the lower left chamber of the heart from the upper left chamber (the atria) doesn’t close properly. This allows blood to leak backward from the atria into the ventricle, and it puts extra pressure on the ventricle to pump it out. To you, it may feel like your heart is skipping beats, fluttering, or beating extra hard.

Sometimes palpitations are a sign that you’ve developed MVP or that your MVP is getting worse. So again, be sure you get any irregular sensations checked. A slight leak isn’t necessarily dangerous, but moderate to severe leaks need attention and care if you want to prevent long-term damage.

Like diastolic dysfunction, we see MVP more in women than in men—and often in younger women in their 30s and 40s. Unfortunately, a lot of people that age don’t think they’re at risk for heart problems so they ignore warning signs like irregular beats. Don’t do this!

Atrial Fibrillation

A-fib is a serious arrhythmia that increases your chances of throwing a blood clot and having a stroke. I was always concerned when patients complained of symptoms associated with it, including heart palpitations.

In people who have A-fib, the atria quiver instead of rhythmically contracting like they’re supposed to. Because of that, blood pools in them longer than normal and can thicken and clot. The clots can then move into the brain and block vital blood flow.

You can live a full and active life with A-fib, but it’s essential that you be on some sort of blood thinner to protect against clotting. When you have your heart palpitations evaluated, make sure your doctor checks for A-fib as the cause.

Types of Arrhythmias

Spinal Misalignment

If you didn’t have this on your short list of heart palpitations causes, don’t worry. It wasn’t on mine, either, until I met Dr. Martin Gallagher. He’s both an M.D. and a chiropractor, and he’s worked with a number of patients whose irregular heartbeats were improved with chiropractic adjustments.

This isn’t something that tends to get written up in medical literature, but it makes sense. Even slight misalignments in the spine can put pressure on your nerves, which stimulates the sympathetic nervous system to release adrenaline, cortisol, and other stress hormones. And stress, whether physical or emotional, can be a major cause of heart palpitations.

On its own, spinal misalignment isn’t as immediately dangerous as A-fib, MVP, or diastolic dysfunction. But it’s worth noting because the chronic stress it causes drives a lot of inflammation in the body. Too much inflammation speeds up the aging process and raises your risk for heart disease, insulin resistance, and other long-term degenerative conditions.

Hypersensitivity to EMF

Finally, I want to mention EMFs (electromagnetic fields) as a troubling cause of heart palpitations. EMFs are the electromagnetic frequencies we’re exposed to from all those wifi routers, cell phones, baby monitors, tablets, and other electronic gadgets we can’t live without.

You can’t touch or see EMF, but there’s increasing evidence that it can affect the body in a lot of negative ways, including overstimulating the sympathetic nervous system. Heart palpitations can be an early sign that your stress response is in overdrive and that you need to take steps to limit your exposure and be smarter with your devices. A good place to start is changing how you use your cell phone. For example, don’t carry it pockets that rest against your body, use speakerphone, and when you can, send a text instead of making a call. I also tell people with EMF hypersensitivity to practice grounding, which helps balance the nervous system and keep your stress response in check.

Don’t Ignore the Warning Signs

If there’s one parting thought I can impress on you, it’s to never ignore heart palpitations.

No matter what age you are or how good of shape you’re in, if you feel fluttering, skipping, or any other kind of irregular heartbeat, get it checked out by a cardiologist. The cause of your situation may well turn out to be nothing to worry about. But if that’s not the case, the sooner you begin treatment, the better off you’re going to be. This is definitely one of those instances when it’s better to be safe than sorry.

    which kind of blood thinners can be safely used for AFib? I am afraid of the new NOAC’s and possible brain bleed. How about Nattokinase/Fish Oil etc?

    I was having heart palpitations due to my thyroid. I had nodules on my thyroid which threw me into hyperthyroidism. I received a total thyroidectomy and the heart palpitations are now gone!

    Hi Brit,
    When it comes to A-fib, blood thinners can be life savers. Natural blood thinners are not generally advisable when it comes to a serious condition such as A-fib. Nattokinase, lumbrokinase, and fish oil are potential options for those can’t tolerate pharmaceutical blood thinners. A natural approach would need to be discussed with your cardiologist and very carefully monitored.

    I have a friend who was placed on Eliquis when it was discovered on an EKG that he was in afib. He received shock treatment and has been out of afib for more than a year now. Why is he still being prescribed Eliquis?

    My name is Jackie I’m 56 years old I have been diagnosed with heart failure and I have really bad palpitations I’m on Xarelto .. metoprolol and I’ve had a heart attack I’m also on fluid medication I’ve been told that I have a left aneurysm that needs to be repaired possibly I have been having shortness of breath night sweats very fatigued and I’m just wondering the benefits about getting it repaired I recently read this he passed that they can do but if you have to have an open heart surgery to get this done so I’m just wondering should I get something done before my symptoms become worse and wouldn’t make me feel better if I got it repaired I’m on entresto I’m beginning to experience a lot of shortness of breath 14 and palpitations have gotten worse I do have an appointment to see my heart doctor soon but I wanted an opinion from a thoracic surgeon about whether the repair was possible and it would make me feel better your thoughts on that.. I also have several stents thanks ..10 yrs left ventricular aneurysm

    I have been on pain killers for a couple years. They switched me from oxycodone to a morphine based pain killer. Can either oxycodone and morphine type pain killers cause the heart to flutter? I’ve had a stress test several weeks ago with a (what ever the procedure is called when a teck runs this gun like thing over my chest). It all came out ok. A couple of extra heart beats did show up on the test. Anyway, let me know, thanks…

    Hi, my name is Marilyn ..I’ve recently started a fast heart rate only at night that awakes me to where I can’t sleep. I have no thyroid only the synthroid for replacement. last checked my TSH was 0.18 not sure if that’s the cause of the fast heart rate at night. my dr lowered my dosage from 88microgram down to 75 but nothing has changed as far as the fast rapid heart rate..When dosage is changed does it take several weeks to see a change

    I am going to be 93 yrs old next month. I was having what my heart specialist concluded was afiib. He started me on a medication I could not tolerate and the other medication was not recommended for my age. I immediately ordered Dr Sinatra’s Heart Healthy vitamins for women and the Omega Q Plus. That was almost a year ago and I have no more symptoms. I wish I could shout this to the world! The reason I chose Dr Sinatra was because a few years ago my daughter was a semi-invalid because of a heart problem. She took her little dog to a veterinary and she mentioned the severity of her heart problem to him. He advised her to follow Dr Sinatra’s advice which she did. She was remarkably better for years even though her heart was enlarged. A sensible diet is required for heart health also.

    I am a 58 year old woman, and recently I’ve have had a lot of palpitations. They’re strong enough that they last a while and make my heart cartwheel or flip – they are quite frightening and now occur daily. I went to a doc / cardio – and he had the nurse do an EKG which i guess was normal. I’m being sent to get the “Boston Test” which I’m told provides much more info than a lipid panel. After that result comes back, he’ll order an Echo test. But after reading the above, I’m wondering why he’s not assessing the palpitations? Until a year ago, I had cholesterol of 220 for about 30 years, and always normal blood pressure, however, since august of 2017, cholesterol has climbed to 310, and BP goes from 140-208 with 150s to 170’s averaging. Should I go to another doc? I feel different. Frequent palpitations, fatigue, and more shortness of breath on climbing stairs. I’m a single mother, and want to make sure I don’t have a heart attack. Father had one at 30 and then pacemaker and aortic aneurysm, and fatal heart attack. Brother had open heart surgery at 40.

    I am a 66 yr old woman and for 2 months have been ill which started with a flu-like virus. I coughed so much that it gave me palpitations and was admitted into hospital for a 24 hour heart monitor.
    I was later discharged when after resting 2 days my coughing stopped and heart rate returned ok and an ECG was passed clear.
    My GP has ordered me to be put on a 24 hour portable ECG machine but that isn’t fitted for another 4 weeks.
    I have since felt very tired, no energy and my heart rate increases with exertion and I start to cough again.
    My appetite is still very good.
    Should I request the portable ECG to be done sooner if possible? Do you think this is anything to worry about?
    Thank you.

    I am 23 years of age, I think I’m a little bit stressed out. At first, i didn’t understand what was happening cause I could feel my heart beat faster one night as I was about to sleep, I sat up and did some breathing exercises which helped me and I slept with no problem but 2 night later, I woke up to use the bathroom but couldn’t go back to bed for a while but after I took warm water, it really helped me and I felt better but then again it happened later that day. what do you think is causing this. My symptoms are heart pounding fast, feeling cold and shaky. I didn’t have fever, headache or any other thing.

    I have a 33 year old daughter who has had two premature children. She developed palpitations shortly after the first was born eight weeks early four years ago. She described them as a thump and she could feel the blood rushing to her limbs. After several visits to the local hospital over a period of time she was told her heart was ok and they were caused by anxiety. She told them they were causing her anxiety and has lived with them since, mentally telling herself she would just have to put up with them for the rest of her life. At 26 weeks pregnant with her second child she had about eight weeks stay in a hospital due to the possibility of miscarrying. The palpitations settled somewhat but did not go. This child is now about 9 weeks old. I visited her last week and found her on the lounge quite upset after her heart had suddenly revved up to almost 160 beat per minute and she could hardly breathe. She didn’t want to go to the hospital because she felt they would tell her it was just anxiety. She said she wasn’t anxious before this happened. I gave her some potassium and magnesium cell salts that seemed to quieten the speed of the heart and it came down to around 100 beats after about forty minutes of giving her these cells salts every ten minutes and checking her pulse rate each time. Her heart was under 100 beats the next day and she said she was ok but tired. She works on a computer and I have told her about the EMF, she was also eating quite a bit of food with salt to try to calm her palpitation, which she said seemed to help. I think her potassium and magnesium levels may have gotten out of whack but I don’t know. Any ideas. Should she get her heart checked again by a heart specialist? I feel heart palpitation that continue to go on day after day for four years can’t be good for the heart, it must have some effect on it.
