[|Human|] In June 2017 I had cardiac arrest. After 4 shocks, died twice I was brought back to life. The doctor did a hear cath and I show no problems (blockages, etc) in my heart and my lungs look good. He states I need a defibrillator implanted due to my heart is only working at 35%. My insurance will not cover this due to they say that the left ventricular is pumping at 48%. I am confused are these 2 things the same? (working and pumping) Prior to this in 2007 I was advised after a heart cath that I had no problems but did show that I had a left bundle branch blockage. So what does it meant for your heart to be working at 35%?
[|AI|]  Hello, Working and pumping are the same things. In technical term it is called as ejection fraction. There must be some confusion, or you must be having two reports of the echo, done by two different observers. Anyway, since you had episodes of cardiac arrest twice you need to get defibrillator implanted and tell insurance company that it's not depends on pumping now as I already had episodes. Hope this helps you and get back if you have any doubts.
