Question : I've been feeling lightheaded and dizzy recently after mild exertion. Just took my blood pressure. Two checks on each arm, all between 120/79 and 111/81. But my pulse, according to the machine, is high ... 120 resting. I am 69 years old and had major surgery in 2012 to remove old blood clots from my lungs and artery (right side pulmonary hypertension). Is my high pulse dangerous?

Hello!

Welcome and thank you for asking on HCM!

I carefully passed through your question and would explain that your symptoms could be related to pulmonary hypertension or atrial fibrillation.

I recommend consulting with your attending physician for a careful physical exam and some tests:

- a resting ECG
- a cardiac ultrasound to examine your cardiac function and structure
- some blood lab tests (complete blood count, blood electrolytes, thyroid hormone levels).

Hope you will find this answer helpful!

Kind regards,
