Was just wondering if anyone suffers from what i from this type of arrhythmia. Been pretty good lately not feeling any funny rhythms now all of the sudden my heart seems to have developed a different arrthymia. It's almost like it hiccups. it beats ok then all the sudden there is a beat that feels like it's trying to kick into a higher speed. I have pac's pvc's and svt i take verapamil, inderal and xanax for anxiety. Now i did make the mistake of lately drinking coffee with caffiene in it, having like one cup a day. I haven't had any caffiene today and now this hiccup beat is here. Just wondering if it could be from caffiene yesterday or the stress i have been under for the last few weeks. It didn't do it while i was drinking caffiene and it didn't do it while i was under stress. Is it possible this kind of an aftermath thing?
