Now back on the home front a big thank you to all those who commented and called wishing me well on my recent hospitalization. The complex technology available to modern medicine is amazing to say the least. More familiar and less amazing was the simple explanatory diagram the cardiologist drew on the whiteboard in my hospital room. As a former teacher that was something I knew how to do...:) Oops DJan commented the diagram makes no sense. Absolutely. The circles are where the veins enter the left and right atrium. That's where they found the short circuits. They interrupt the electrical pathways by burning (cauterizing) them. Simple huh... like finding a needle in a haystack.
