Question: Hi I have some questions regarding my PACS. I was feeling palpitations several on the ago and was sent to a cardiologist. He ran several tests including an echo, ECG, stress test, holter monitor, and loop monitor for 24 hours. The results of the echo showed a structurally normal heart with some trace regurgitation. Which he said was normal in most hearts. Every function and size of the heart was perfect. The holter monitor picked up 925 PACS over 48 hours. 2 bigamy cycles and 3 couplet cycles very short. It only showed 1 single ventricular beat. I suffer greatly from anxiety and panic especially lately. I have had episodes where my heart will race at 160 BPM through the day but very short 2 minutes or less and slows down when I do deep breathing and drink water. The PACS I feel at night before bed and when I wake up in the morning. I don't know if it's happening when I sleep. I am worried about this but my doctor says they are benign. He didn't explain anything toe which freaks me out more. Is that too many PACS I've heard people can have tens of thousands in a day but I don't know. These tests were 5 months ago. How often do I need a repeat of the tests? My cardiologist told me at least 3 years. I eat very well and have lost 75 lbs over the last 10 months. My resting heart rate is around 56 -60 depending on the time of day. Doctor says this is fine don't know if I should worry.  

Here is the results of my 48 hour holter monitor  

198000 total beats  

26% in bradycardia  
12 % in tachycardia  

Lowest heart rate was 50 at 5 AM during deep sleep. 
925 PACS  
915 We're single  

I was told supplements can help with palpitations such as magnesium, potassium, omega 3 and vitamin c and b 12. Should I try this and is this safe to take?
