During my recent annual physical, my doctor asked me if I was experiencing any health issues that he should be aware of. My only real complaint other than the normal stuff related to aging was the fact that I felt my cardiovascular endurance had diminished far more so than my contemporary soccer teammates. I expressed the same concern five years ago and he ordered an echocardiogram stress test. It revealed some undesirable EKG waveforms but my coronary blood flow was deemed to be good. He thought it would be a good idea to get another stress test to see if anything had changed from my baseline. The results of the test I did today showed the same anomaly in my elevated heart rate but no change from my last test. This test did not include the ultrasound component and based on the outcome, I have to come back again and repeat the whole thing again for the more comprehensive test. The good news is that we live so close to the hospital now that it was faster to walk there than drive. I could also see our house while running on the treadmill. It is located in the clump of trees in the background. Below on the left are my at rest waveforms with my elevated heart rate waveform on the right. Apparently, my pattern shows an ST-segment depression outside of the normal range which can be indicative of reduced blood flow to the heart. According to my very friendly technician, my pattern was identical to the one five years ago and he is fairly confident that a repeat of the echocardiogram will not turn up a blood flow problem this time either.
