Hi guys, well i really don,t know what to do i suffer from benign pvc's but last night after drinking way way to much caffeine and having a heavy meal my might all of a sudden went into a bout of tachycardia which has never happened before. it was going so fast i couldn't even count. i was so scared i took some xanax and had my wife try to calm me down. after 20-25min of this my heart started to slow down i am so scared right now that i can't even think straight. has anybody have had this happen to them thanks
