This evening I went to the hospital for my cardio treadmill test. Result: everything is back to normal. The test was quite intensive and the physiologist who did the test complemented me on my recovery time. From a bp of 240/90, heart rate 170, I recovered to bp 110/70 and heart rate 66 in about 1 min 45 seconds. To say I'm pleased with this is an understatement. I can now turn my attention back to the trailhead this weekend. Can't wait. Notch this one up as yet another success for the 50+ brigade!
