Unexpected ICD shock

[Rudy777]

Hello
Yesterday, I went out for a five mile walk. Normal pace no running but faster than a stroll. Felt a little "loopy" a few times. Drank some water and kept on going. Got back home and we started to organize stuff for dinner and I felt my chest going biserk and then ...SHOCK. My ICD shocked me and since then I have felt normal but very unstable in the heart. Slept horribly due to that welling feeling in the chest ...arrythmia? I have measured my pressure and pulse when I feel like something is going on and occasionally the pressure has been as high as 133/88 with a pulse of 47 and as low as 87/48 with a 55 pulse. I am on beta blockers (sotalol and coreg). Prior to that I had very salty fish the previous day and almost 2 pints of Guiness draught which I was in the process of finishing (a dark beer, for the 'nonusers'). Maybe I should have stayed with the Pinot Noir? I felt tachy the previous day when I bent over to take something from a bottom drawer and I think I came close to shock too then. ANy thoughts? I am getting very frustrated wit this condition. We have suspected everything from catecholamines to arrythmia but after a heart failure last summer which is why I have the ICD, I am not sure what else to think. Is there any body out there with this stuff or suggestions?

A first shock from an ICD is almost always unexpected. If you felt well before and after the shock, and have not had palpitations lightheadedness, dizziness or shortness of breath, then you don't necessarily need the device interrogated. If not then contact the implanting cardiologist and have the device checked.
Your medications are appropriate, but you should not be drinking alcohol in large quantities with these as alcohol may induce your liver's detoxifying ability for these drugs and hence lower serum levels causing the shock. Sotalol is partly metabolized by the liver, as are most beta blockers.

I'm sure you will get a response from the doctor on this site but have you had your ICD interrogated since your shock? If not, then I would suggest that you do right away to find out what your heart was doing before the shock. Only your doctor can tell you what has happened by looking at the info from your ICD.
Take care
