... with a rapid and irregular heart beat. I had my wife rush me to the nearest hospital. I was in a total and complete panic. It was traumatic. I was in the hospital for a couple of days. I went back into normal sinus rhythm within 24 hours through chemical cardioversion with Flecainide. I am still an emotional wreck! I'm consumed and worried when the next attack could be. I have since woken up several times throughout the night with a rapid heartbeat without the irregular rhythm. I am emotionally breaking down. I am petrified of another attack. Can someone please help! I feel like I am going through a war!
