Heart Disease

[linracer]

did alot of exerting work building a deck and also in the heat.  got weak and pulse jumped up to 139 for several hours.  I had forgotten to take my bp meds in the morning.  when pulse goes that high how long should it last before it drops down again,

I have to agree with Erijon/shadow on this, it was the effect of the heat and probably lack of fluid. I remember cutting the front hedge last summer on a very hot day, I had to go and lay down for 15-20 because I felt dizzy and my heart rate shot up. It felt like my blood pressure had dropped considerably. I drank plenty of water and soon recovered but waited until the temperature had dropped a bit before continuing :)

working in the heat makes your heart rate go up too

It sounds like you may have gotten dehydrated which will cause low BP and your heart rate will increase as your heart tries to compensate for your low blood pressure. Once you fluid volume comes up, your BP will rise and your heart rate will usually begins to drop to normal levels. Just another possibility.

Just my two cents,

To provide a perspective, if your fitness level is good your recovery rate after your work and hot environment should be below 100 within 2 minutes at rest and away from the heat. A slow reduction in the heart rate after exercise is beneficial to the heart. However, if the heart rate has not dropped by more than 12 bpm one minute after stopping exercise this may indicate health issue.

Your heart rate may remain high after exercise if you have tachycardia, a condition that affects the one or both sets of chambers in your heart. Tachycardia causes your heart to beat significantly faster due to its effects on the electrical signals that control your heart rate.

Hope this helps.  Thanks for the question, take care,
