please doctors in the house, I hav noticed that sometimes when I wake up in the midnight to ease my self or in the morning, I wake to feel my heart pounding fast. Though not every day, but it's giving me concerns. Pls I just want to know if it's normal or not, and what might be the cause before seeing a doctor. Thanks!

Go and have your blood pressure checked. To erase the doubts of you having hypertension.
