Not sure exactly but somewhere around 1400. Cardiologist said one of the highest the has ever seen. I didn't feel any effects of this for 3 1/2 years, remained very active. Then I started to have some issues when I was hiking or biking, where I would have to stop and let my pounding pulse settle down right after I would get started. Because all previous tests found no issues the cardiologist said the only option left was to take a look with a cath. I ended up with 2 stents. I feel like with stents now I have less energy and get tired quicker when active. I do a lot less than I did a year ago.
