Hello thanks for posting here. I have gone through your description. Since you suffer from high blood pressure, some of the above symptoms like pounding heart, hot inside body can be due to high BP during those episodes. Feeling of tiredness, fatigue, listlessness can be caused by a number of factors. Going by your history and my experience, I consider the following probabilities here. First is vitamin D deficiency which can cause tiredness, fatigue. Get your vitamin D levels checked and if its low, correct it by taking vitamin D supplements usually the once a week tablet. This will Chat Doctor.  Next possibility is heart disease which can also lead similar symptoms. Don't worry, it's better to be safe than sorry. Since you have a high blood pressure history, and your age is 73, i advice you to undergo a cardiac check up which should include an ECG, 2D echo and a treadmill test. These tests are very sensitive to evaluate cardiac disease. So to summarize I would advise you to do a it D levels, fasting and post lunch blood sugars, ECG, 2 D ECHO and treadmill test. Wishing you good health regards
