I was put on the king of hearts monitor yesterday. Have had the older models before. I have palpitations, skips, misses. etc. No pain or shortness of breath. This thing is a real pain! It has the monitor and then goes into the receiver when I hit the monitor. All recorded. My question.. I understand there is an improved version that is just one electrode, nothing else! It all records in the electrode???? Are you familiar with this?
