I'm doing a follow up stress test today after a stent was put in last week. They asked me to not eat for 4 hours prior to the test and I finally got them to explain it was because some people threw up. I laughed. It's just ten minutes of a hard effort. Today's goal will be to get them to let me continue pushing to a real, stressful, maximum effort and for me that is WAY beyond the point where they normally stop.
Yeah, this isn't a performance study. What they are looking for on the ECG are signs of muscle that is becoming oxygen deprived. When a section of muscle is not getting enough blood flow, it changes the electrical characteristics of the tissue, and that appears on the ECG. They take you to a certain heart rate based on a protocol that is designed to reveal cardiac muscle ischemia, not your max performance
