Recently had my ICD replaced after having had a Medtronic for approx 8 years. Did fab with Medtronic , activated a couple of times, but all in all very good. Believe it or not never needed the beta blockers even!! Battery depleted so replacement necessary. I had a St Jude ICD fitted not even been in 6 months and it's activated. My confidence is shattered, I have had to go into beta blockers and still don't feel well😓 Could the device settings need adjusting? I am told the settings are the same, but somethings not right! I don't want to continue to increase meds. I just want my life back. I am too frightened to do .anything alone. Oh forgot to say I have CPVT! I just cannot carry on living like this 😓😓😓😓😓.
