I have spent the last hour reading the many posts, and one comforting thing is I'm not alone with all the heart issues! I'm 28 I just had my second ablation for an AVNRT (SVT) I thought the first was succesful until one year later I had a severe episode where the heart went to 240 bpm and had to go to ER to get it dropped. A month later they did another ablation. The first night after the ablation I had some of the worst epeisodes of Tach, irregular heartbeat, and it honestly felt like another SVT. They kept me another day, and the heart eventually returned to a normal sinus rythym. They switched my metroprol to a diltizem. 120 mg twice a day. My heart rate has been ok, but standing up siting down and moving, the heart rate jumps up, it skips around. and feels like it is ready to go into a SVT. This normal? Its only been 5 days since procedure. I have always battled PACs and PVCS along with the SVT. Anyone know of better drugs? Should I expect to feel better soon? I hate standing up as I fear the heart will go on its own, and I will be stuck in hospital again. How much does stress and anxiety play into all this? It has obviously been a long few years, and I just want to live a semi normal life and not live in fear of what my heart will do next! Tanks all for the input
