I posted this on medical procedures but think it's more relevant here? I have biventricular ICD since 2010 and it has never fired offically. I am sure if fired for the first time yesterday but hospital say remote interrogation shows it didn't. I am at hospital this month to have ICD check which will give me a 2nd opinion but right now I feel like an idiot, total idiot. Here's what happened, I was asleep and woke with a jolt, having saw a flash of blue light, my heart rate was fast and hands tingling. I felt like something had happened to my body. Weirdly when I awoke I was dazed and immediately thought I had been electrocuted and was going to search for the offending cable/plug socket in the bed covers! Later I felt pressure in the middle of my chest. I NEVER felt any kicking anywhere, not chest/back or side. Do you think my ICD fired or do you think I need to seek out men in white coats? Thank you all.
