What Causes Tachycardia And Fatigue?

My boyfriend has been experiencing tachycardia without significant hypertension. His resting heartbeat earlier was 110 then after a nap 81. This was at 5, we were just lying next to each other talking. Now, he said it s happening again, while he s driving. He has also been experiencing more fatigue than normal.

HI, thanks for using healthcare magic

It would be best for him to see his doctor for assessment. Increased heart rate can be due to different possible causes such as : (1) thyroid disease
(2)anemia
(3)infection
(4)side effect of medications
(5)intrinsic problem with the heart

To find the cause, he would need to be assessed by his doctor. This assessment would include physical examination and tests such as complete blood count ,thyroid function tests and an ECG which would look at the rate and rhythm of the heart.

I hope this helps
