What causes severe heart palpitations?

Question: I have been experiencing heart palpitations for 18-20 months - consistently. I am being seen by a cardiologist, but the time between visits and attention is not adequate. I have had EKG, ECG, Zio Patch,Chest X-Ray, Stress Test and blood work. On Dec 22, I experienced an AFib event which put me in the hospital where they administered cardioversion. I went on a therapy of Xarelto for 30 days. I continued to take Metoprolol and Multaq, and now a baby aspirin to replace the Xarelato. While I have not had another Afib event, my palpitations are getting and have been far more aggressive and longer lasting. Currently the doctor is not alarmed and wants to continue to say the metoprolol "should" be keeping the palpitations at bay. By the way - all the tests show PVCs... but I assume these are benign since the cardiologists has not prescribed anything else. I am wanting to know, if I am missing something, should I be doing something to drill down further on this? I am afraid to exercise nor do much else. I am 52 yr old male in otherwise good health. 6'1" 195 lbs I think.

I would explain as follows:

Detailed Answer:

Welcome on HCM!

I passed carefully through your medical history and would explain as follows:

a - After that successfully converted atrial fibrillation episode, it is necessary to be always attentive of possible recurrences. In this regard, it is important to avoid potential triggering factors such as alcoholic or caffeinated drinks, avoid close smoking contact, maintain a regular life-style and sleeping profile.

I would encourage you to keep being physically active and not be afraid of any deleterious effects of training. Of course it is important to follow a properly scheduled training program under supervision of a qualified fitness expert.

This will improve your physical endurance, cardiac chronotropic response, blood circulation; decrease level of anxiety and burn excessive calories.

b - As you actually have left behind that AFib episode and a month has passed, it is rationale that anti-coagulation has stopped and an anti-arrhythmic maintaining therapy established.

Coming to this point, what is more important seems to be quantification of this maintaining treatment. This is done by monitoring your heart rhythm for a longer period of time. In this regard, it is recommended 24 to 48 hours ECG monitoring (Holter).

This is also valid for your recurrent PVCs.

I would explain that PVCs could not be a marker of a serious cardiac disorder as far as a normal cardiac structure and function have been concluded by the performed tests (cardiac ultrasound, cardiac stress test) and no excessive amount of them is confirmed by Holter monitoring.

So, the best thing to do is perform periodically Holter monitoring for two main reason:
1) screen for possible complex cardiac arrhythmia occurrence (including recurrent AFibs) and quantify the exact level and day-night trends of PVCs.

2) explore the effectiveness of your maintenance ahti0arrhythmic therapy (by comparing consecutive Holter tests). Metoprolol and Multaq are also recommended drugs for PVCs.

So, you should relax as your therapy is properly targeted!

But, what is important in this period is an appropriate surveillance of cardiac rhythm issues and also checking other possible triggering factors of cardiac arrhythmia, such as:

- a pulmonary disorder (it is recommended pulmonary function tests and arterial blood gas analysis),
- thyroid disorder (checking thyroid hormone levels),
- electrolytes imbalance (checking blood electrolytes level),
- inflammation (PCR, ESR),
- liver and renal function tests,
- glucose metabolism disorders (fasting blood glucose, HbA1C)

After avoiding the above prescribed triggering factors and assuring that the above mentioned imbalances are not present, it would be more easy to control the level of those benign PVCs and properly judge about the therapy effectiveness (through periodic Holter monitoring).

You need to discuss with your attending physician on the above mentioned issues.

Hope to have been helpful to you!

In case of any further uncertainties, feel free to ask me again.

Kind regards,

Thank you Dr. IIiri -

So you know - I have been Holter Monitored (Zio Patch) a couple times, but will suggest we do it again so they can see if there is any Afib present during the palpitations. Also, the day to night PVC's have changed. This could be pure anxiety as well.

I have not been checked for any pulmonary disorder or inflammation PCR and ESR, but have been checked for thyroid, electrolytes, liver and renal and glucose metabolism. I will make sure though.

I don't smoke, drink nor consume caffeine. I truly try to stay away from all possible triggers as I hate these palps.

Your reassurance though with exercise and telling me to relax is very helpful. I am scared to death to exercise and always worried I should be doing, eating, taking something different. All my blood work comes back good as well. No cardiac enzymes, and nothing out of the ordinary.

Thank you

Detailed Answer:
Hello again!

Thank you for the additional information!

I am glad that most of your tests have resulted normal. This is a very reassuring fact that nothing serious is going on with you!

So, just relax and don't worry about it!

You can feel free to exercise as you like. Of course aerobics, yoga and recreational sports are more recommendable. I would just recommend avoiding straining physical activity (like weight lifting or racing).

Anyway, if you wish, you can perform the additional recommended tests in order to exclude every possible underlying causes.

Hope to have clarified some of your uncertainties!

Let me know about everything!

Wishing good health,

Dr. Iliri

Recent questions on  Cardiac arrhythmia

doctor1 MD

I recently had an ECG after an abnormal EKG. The ECG showed vent. rate 108bpm Sinus tachycardia, PR interval 158 ms, possible left atrial enlargement, QRS duration 88 ms , nonspecific ST abnormality, QT/QTc 368/493 ms, abnormal ECG, P-R-T axes 70 48 58 and prolonged QT. The cardiologist didn t seem very concerned and felt the abnormality was because of the medication I was taking - remeron for sleeping; I suffer from chronic insomnia. I have been on this medication for over two years and have never had any side effects or problems with it. In the past three-four months, however, I have been experiencing chest pains, some severe which is why I went to my physician to get the first EKG which showed a fast heart beat and was referred to the cardiologist for an ECG, EKG and a stress test. I was only on the treadmill for maybe 4 1/3 minutes before I experienced SOB and chest pains. They repeated the ECG and I was told it was abnormal and to discuss my medications with my psychiatrist and that I had nothing to worry about. When I see abnormal ECG, EKG and am taking nitro tablets with a family history of heart disease (father COPD, CHF and angioplasty; grandfather died of a heart attack), I have a tendency not to believe the doctor. I have not even been contacted by my physician for a follow-up visit. Should I be concerned. Cancer also runs in my family; my father died of colon, liver CA and I am breast cancer survivor. I d appreciate your comments. Should I seek another opinion? Thanks, Mary Kopco YYYY@YYYY I am a 61 y.o. white female, 137 lbs w/ hx of cancer (bilateral mastectomy and hysterectomy for CA of uterus), osteoporosis and osteoarthritis, high cholesterol (328), allergic to any statin drugs, being treated with Zetia 10 mg 1 x/day. Presently taking nitro tabs for chest pain, oxybutityn for overactive bladder, clonazepam 1mg 3x/day for anxiety and depression. I look forward to your response. Thank you.

I am a 24 year old male. I have PVC s and PAC s. I am extremely active and in great physical condition, I spend 1.5 hours, 5 days a week working out. I am 225 lbs, 8% body fat, and 6ft tall. I take no supplements. Recently I have been having some worrisome palpitations. Usually in the early morning my heart will either beat extremely fast (180-250bpm) for a few seconds accompanied with near syncope and SOB or it will beat erratically. I had an extended episode (30 seconds) of appx 200-250 bpm brought on by a sprinting session about 2 months ago. That is when these strange rhythms began. Normally I feel my PVC s, so I am very aware of my heart beat. My heart feels strange like it is tired latley. What could this be? I am worried about VTach, but as I do not have insurance I am wary of going to the cardiologist. What should I do? Thank You

i am 38 years old, 6'5" and 330 pounds. I've been having severe heart palpitations with shortness of breath that seems to rise up my body. First i get a warm feeling in my left ear, then i get very dizzy and start seeing white spots, then it feels like i'm losing oxygen to my head and i start to blackout. it usually goes away after i close my eyes and sit still. i have been to cardiologists who told me that i have high blood pressure and could lose weight, but my angiogram, etc. all prove normal. i am taking a beta blocker (cardovilol or something) plust a high blood pressure medication.

Hi. I am a male. As long as I can remember, i have experienced a sharp, burning chest pain that occurs randomly. It does not radiate and usually only lasts a few seconds. It is not brought on by exercise. I also occasionally experience palpitations. Sometimes, it feels like my heart stops and skips a beat and then continues. I also can feel my heartbeat sometimes and it beats fast and hard. My usual resting heart rate is about 103. My BP is about 128/76. I have panic attacks also. Occasionally, I feel lightheaded which usually only lasts for a few minutes and is followed by extreme anxiety. I sometimes get nauseous and have irregular bowel habits. Sometimes I am constipated and other times I have diarrhea. I have seen my doctor and had blood work and a EKG done. Palpitations did show up on the EKG but my doctor says they are not serious. Some people have suggested I have acid reflux. I seem to have some symptoms of MVP but I was never diagnosed with it.

I have high blood pressure(165/110) and was put on Lisinoprin 3 weeks ago and it has come down about 30 points...however i have head aches and have shortness of breath . I wake up at night and feel like i'm not getting enough oxygen . I weigh 260...

doctor1 MD

I was diagnosed with attrial flutters ( arrhythmia ) and the cardiologist did a cardio version and a subsequent EKG showed the condition was corrected. The doctor has me on Xarelto and a beta blocker . I feel fine and I am wondering if I can drink...

My husband is 80 years old and has been diagnosed with congenial heart dease. His heart is only pumping half the speed of a normal heart beat. And now his lungs are filling with fluid. He also has Alzheimer's.
