I cried on the way home from the cardiologist.

To make a long story short, I get tachycardia daily, usually after eating.  It doesn't last too long, usually not more than 5 - 10 minutes, and I can mostly get it to stop with a valsalva  pressure or by coughing.  It's mostly after eating a little processed food,   which contain sulfites (preservatives), to which I have found out I am sensitive.  I had a heart attack 3 1/2 years ago when the tach triggered a coronary vasospasm which caused a plaque rupture. 

Hi Alcie

Thanks Kitt, Sasha and Cinnamon. I appreciate the suggestions. I'll talk with my PCP about a different cardiologist, but I don't want to get rid of the current one because he's the best at what he does when it comes to getting a stent. I may be getting another clogged artery - can't walk up my hill easily again. I had to insist the last time I got a stent that I felt like I was going to have another heart attack. I don't want another cath, but maybe that's what I need.

I looked up the Zebeta, but it says nothing about rhythm, only lowers pressure and rate. It looks like just another beta blocker. My heart rate can drop below 50 at night now, and relaxing the blood vessels with meds hasn't stopped tachy events in the past. My regular rate is fine. I get tachycardia events, usually, but not always, after eating processed foods (even stuff like corn starch or bread). My BP ranges all over the place from 103/65 to 127/85.

I'm still hoping to find something that controls heart rate without relaxing the blood vessels.

I also have tachycardia.

Why don't you tolerate betablockers? What are your side effects?

Maybe you should try a different one? Have you tried metoprolol? They even give this one to pregnant women with heart problems.

You should probably be medicated because tachycardia can occasionally lead to a life threatening disease called cardiomyopathy.

Please seek more medical advice.

Best wishes.
