Voltage on the leads
I had an AV block resulting in a low hearth rythme of 37 during sleep. I now have my two lead Medtronic pm for one month and everything seems fine. Today during my control visit however the doctor told me that the upper lead uses 1 volt and the lower lead is using 3 volts and that they prefer to move this lead into another place in my heart to get to a lower voltage. My question, is this really necessary? Is the lead not well attached or is it not my heart that needs the 3 volt in order to function? Anybody with same experience?
