3 years ago they put in a defibralator. 4 months afer placement it fired 3 times back to back due to a malfunction. i spent 6 days in the hospital and they adjusted it. i have hated since, and fear it now. it has fired 2 times since but on a low scale. i was able to handle that the other time it fired 3 times it was on the highest joilt. it knocked me to the ground. anyway now they tell me the modle i have is defective. something wrong with the battery, and i need to replace it. my dr. says my heart is weak and it would be a big risk to put me to sleep. what do i do? it also works as a pacemaker and a arrithmia converter, i have v-tach. and atrial-fib alot and this does convert the arrithmia if my heart doesnt do it its self. i know i have to make a choice, im so scared i just dont know what to do. i fight daily for my life and will never give up, i love life, im happy, i do have bad days but who dont, i thank god for the good ones and cherrish them. the dr wants an answer by jan. 15 my next visit. please pray ill make the right choice. my medical dx are chf, cardiomyopthy, ashd, 3 mi"s, 5 vessel by-pass, diabetias,cad, well all those heart dx"s that pertain to the heart. i did get a port-a-cath, that has been a life saver, no more sticks.i thought everything was going well, now this.
