I was looking to send a personal thank you but could not find a correct email. I was being tested to make sure I was ok for a hip replacement. Dr Bloch noted something called an inverted T wave on my ECG and compared it to one 9 years earlier. It was different. I had just ridden 50 miles on my hand cycle and felt ok so I was more than willing to blow it off. Well, I had abnormalities on my nuclear heart scan. I had a 99% blockage in one coronary and 80% in the other. They placed 4 stents.
