@wandeljw,
ok..I'd say I'm dropping it as well, but that would be redundant and calling additonal attention to it.
I do want to say my thoughts and prayers are with Mr. Chai and Chai, as well. I empathise and sympathize for what he's going through. I especially can identify as I have a defib-pacemaker implanted 6 yrs ago for my severe arrhythmia brought on from obstuctive cardiomopathy. As a point of info, to those who may not know, this (mostly non-invasice) procedure goes smoothly 99% of the time.
That being said, a nightmare scenario can occur if the feedback loop (with connection) is interrupted and the logic in the defib senses through the software and the lead that the heart is not beating within the safe limitations. The fact that it did this repeatedly is ONE of the worst possible scenarios. The absolute worst is it not firing at all when your heart falls outside of the "safe" parameters. To be shocked once is not fun, to be shocked repatedly all the way to the hospital...I just can't imagine it.
Problems can arise after implantation for those who are very active and if they lift a lot as they may tear the lead which attaches to this AV node of the heart muscle. The body, in its infinite wisdom, after healing, starts to cover over the lead with tissue over a period of time. Sometimes people who are in construction and in the building trades are more prone to tearing this lead (lifting left arm over the head). A minor outpatient procedure reconnects the lead with no huge hassle. While I was in having my first unit implanted a contruction worker was in having his lead reconnected.
FYI, every 3.5-6 yrs , you get a new unit implanted as the battery runs out.
It is the common medical practice to replace the unit rather than just swapping the the batteries out. This is often done as an outpatient surgery in 6 -8 hrs if the lead does not have to be replaced. In some cases, they'll hold you overnight for observation. My last was done in oupatient surgery as they used the same lead as it was tested as 100% relaible (not one of the defective, easily-fratured ones in the news).
Anyhow all this is info for those wondering about the reliability and effectivenss and procesdure that is donw to implant and live with defib- pacemakers.
And, once again, my sincerest sympathies go out to Mr. Chai in this very scarey series of events. One shock can be tolerable, but several non-stop shocks is what I consider one VERY bad hair day.
