Greetings, as a survivor of a heart attack and six-bypass open heart surgery, I personally am health cautious about being in temperatures below 70 degrees and above 80 degrees F. I also mind my physical activities when the humidity is not favorable.
Advice given in an article excerpt “Extreme Weather and Your Heart: What You Need to Know When It Gets Really HOT!” by SCAI SecondsCount. http://secondscount.org/heart-condition-centers/info-detail-2/extreme-weather-your-heart-what-you-need-to-know-w#.YKv-caEpDIU
“When the temperature reaches 70 degrees Fahrenheit (21 degrees Celsius) and the humidity is 70 percent or higher, your heart has to begin to work harder just to cool your body. When the outdoor temperature climbs into the 80s (Fahrenheit) or high 20s (Celsius) or beyond and there is high humidity, the risk to your health also rises. If you have heart disease, it is especially critical that you avoid exercising when the temperature and the humidity are both high. Consider delaying any intense exercise until the temperature has dropped and the humidity has reduced, or consider doing your doctor-approved exercise where the weather won’t be a problem, such as in air conditioning or in a swimming pool. “

I know this post is a little old, but I'm having the same issue while playing Pickleball. I'm 59 and had a CABG eight years ago and am doing great. My resting heart rate is high 50s. My blood pressure is 105/65. I work out twice a week with a trainer, I hike (usually 8 miles with 1,000' of climbing involved), I run, ski in the East and in the mountains out West, and…I love to play Pickleball! 😃. While running, I will walk if I hit the low 160s, but it seems like my heart rate likes to stay a little high while I run. I also just had a stress test two months ago where I hit 12.9 mets. Having said all that…I just started playing Pickleball this summer, and, when I play, I wear a fairly new Garmin sports watch. Initially, I didn't look at my watch because I was having fun and felt great. It just didn't seem necessary to pay attention to it. Then one hot humid morning, I felt a pretty tired after a fairly aggressive game, and sat down to rest after the game. When I got home, I downloaded my stats into my phone, and, holy cow(!), I was playing in the 170s (with a spike to 182!). I had no idea. Btw, my watch is programmed to pick up AFIB, and I received no alerts. I then looked back at all the times I played this summer, and, yep, 170s. Note that the high heart rate wasn't immediate, it took a few games to get there and would settle down quickly between games. During my annual checkup two weeks ago, I talked to my Dr about it and he wasn't too phased due to my overall good health and activity level, but he said to rest and cool down when it got high like that.Part of me thinks there is a quirk in the watch that causes it to read high during this fast twitch muscle stuff. So I'm going to try wearing a chest strap to see if the readings are consistent.Otherwise, I can't explain it. It gets really high, but I'm not that out of breath (not like when I'm running and it gets in the low 160s). It now weirds me out a bit, and so, as my Dr instructed, when my heart rate climbs up I'll finish a game and just sit a bit till my heart rate comes down (which it does pretty quickly), and then play again.
Does anyone else have this happen to them?
