Breathless

Today I took a long lunch hour and had my cardio stress test. The first half hour was fine, just lots of readings with me mostly lying on my left side. Then they strapped the box holding all the leads around me so my gown actually closed, and I went on the treadmill. The goal was 6 minutes, I made it to four and a half before painting so hard I couldn't catch my breath any more. So, not optimal but the heart rate did get up to almost 130 (the goal) even with my beta blocker meds, which I thought was pretty good. Unfortunately, the shortness of breath brought on coughing fits that lasted through the day and into this evening, not to mention a good deal of weariness, so I fear I'm not good for much of anything...
