Hi, I had a Boston Scientific 2 lead intra venous ICD fitted 4 weeks ago.Background
From discharge home the first night going to bed and lying on my back I experienced substantial shocks which were impacting my diaphragm. The following day I was experiencing runs of small pulsing , up to 10 beats at a time. I was also experiencing severe postural hypotension. The device is fitted primarily as a secondary protection against a potentially fatal left ventricular tachycardia. The primary protection is provided by bisoprolol.The atrial lead was set to pace at 60bpm to counter my natural low HR circa 40bpm resting from dropping to unsafe levels at night. This lead is failing by not shocking correctly although I understand it is sensing correctly. There was not a lot of confidence however when it came to explaining the interactions that were giving me the symptoms. The offending lead was adjusted to pace at 35bpm effectively switching it off and all the symptoms disappeared!
Questions
Does anyone have any experience of being re opened up to check the device lead fixing points?
Does anyone have any experience of having a lead replaced?
Does this experience include removing or leaving the offending lead in situ?
We're you given any explanation or analysis of the cause of the failure?
Was it fully successful and no further problems?
Was there any evidential excess battery usage recorded that would ultimately shorten device life?
Are there circumstances where the entire device and leads were replaced?
And the not so good question has anyone experienced ongoing issues or bad experiences associated with incorrect shocking further damaging the heart and causing more disrupted nerve pathways? How was this discovered and resolved?
Has anyone subsequently had a different device fitted eg sub cutaneous ICD?
I hope this set of questions is not too specific.
I have a date coming up where I feel I will only have a limited time to reflect 'how we got here' to being immediately prepped for theatre for the consultant to examine and mark their own homework. I doubt much time will be allocated to any introspection or explanation given my existing experience.
