What Causes Arrhythmia?

default
Posted on Mon, 27 Apr 2015
Question:
Hi I had a full cardiac work up 2 months ago. Everything showed a structurally normal heart with some trace regurgitation and holter showed 150 PACS and rare pvcs. The last 3 or 4 days I have been getting more palpitations. I could feel more. I'm not sure if I'm just thinking too much and I feel them more or I'm actually having more. I notice I get more before bed or when I wake up in the morning and sometimes after I eat. Are these still benign? I do have anxiety and some acid reflux. My resting heart rate is around 56 bpm. Also does these palpitations lead to worse arythmia?

Brief Answer:
Nothing to worry about is happening to you.

Detailed Answer:
Hello XXXX!

Thank you for asking on HCM!

I have passed different times through your medical history and reviewed your sclinical scenarios. I am glad to confirm you again that everything seems Ok, and in stable comditions. You don't have to worry about those palpitations before getting to bed and immediately after waking up in the morning. Both these periods of time carry a large burden of silence and self-reflexive thoughts, so it is easier to have more smart common senses, and experience even tiny stimuli. Morning time is a bad advicer too (because of a higher level of cortisol and catecholamines). So the triggered stimmuli may be perceived in an exaggerated way. So relax! You are not actually in a dangerous situation, no life-threatening arrhythmia is comming after those few ectopic beats.

Hope to have been helpful! Greetings! Dr. Iliri

Hi Doctor Thank you for your response. I noticed lately I am more aware of my heartbeat. Can this be due to anxiety? Even when my heart is not racing I can sometimes feel it. Also I noticed my heartbeat is very irregular. Still in sinus rhythm but sometimes the beats are not spaced out evenly. I'll have some quicker and some slower beats. Is this normal?

Brief Answer:
Anxiety plays an important role on your complains.

Detailed Answer:
Hello again dear XXXX!

Don't worry about your unequally spaced sinus beats. You are a young man, and this is a normal finding in young people. It is called phasic sinus arrhythmia or respiratory sinus arrhythmia (instantaneous modulation of heart rate by respiration phases). So you should relax regarding this issue.

My personal opinion is that anxiety plays an important role in what you feel. Your fixed idea of any possible rhythm disturbances, and your fears about a potential life-threatening arrhythmic complications are a source of developing stress and anxiety. You need to engage yourself in physically active and intellectually extensive activities, in order to avoid those unpleasant thoughts, that pevade your mind.
At the end, I want to reassure you that nothing abnormal and dangerous is happening. Relax and don't worry!

Best Regards! Dr. Iliri

Hi Doctor Thank you. One last thing before I close the discussion. When I got out of bed this morning my heart was racing around 150 BPM. I know you said in the morning it's normal to have some tachycardia and varying heart rate. Is this heart rate too fast or dangerous?
Also I was sitting in my car today when I felt some etopic beats. They were quite strong. After the beats my heart started to race. I'm not sure if it was anxiety or because of the beats. I felt a little light headed. Could it be anxiety?

Brief Answer:
Nothing dangerous with your heart, just treat your anxiety.

Detailed Answer:

Hello XXXX!

Regarding your last question, my opinion is that you are facing with a lot of stress and anxiety. They are perturbing your mind and your ability to decide the boundary line between the important issues and unimportant ones. Anxiety is affecting even your common senses.

Remember that heart rate is the most dynamic parameter ever changing, and no one is able to find exactly the same values in different situations. You need to treat your anxiety, not your heart. I see nothing dangerous with your heart functioning.

You can perform routine cardiac check ups, periodically. But you should pay attention to your anxiety immediately, right now. This will relief your mind and your thoughts, as well as your heart from racing too fast.

My Best Wishes! Dr. Iliri
