All wired up and screwed up now. The wire leads actually are screwed into the heart muscle---told you I was screwed up--lol. Supposedly it only kicks in if I fibrillate or the heart stops. Mighty sore, they put the device into the upper pectoral and every time I wiggle my toes it hurts--not really. Did not know but cannot be welding or even running strong electrical tools(circular saws). Sure hate to sell the wire feed but that is just the way it is. Will keep the AC/DC "buzz box"--just in case. Have enough battery tools to get by w/o using the electricals. Anyone else have an implant? Any problems?
