In the past, many people mistakenly believed that only a fast heart rate was a precursor to blood pressure issues. However, recent studies have shown that a slow heart rate and low blood pressure are closely related. In fact, people with low blood pressure and a slow heart rate may experience numerous health complications.

I recently had a heart physical examination because I was experiencing occasional sharp pains in my chest and a fast pulse, reaching 110 beats per minute. I also felt fatigued. During my general physical examination at the heart hospital, I underwent several tests, including an ultrasound, blood test, electrocardiogram, and stress test. The doctor concluded that everything was okay. However, I sometimes notice my heart rate increasing to 90 beats per minute during light activities, and I feel fatigued. My question is, is it normal to experience a rapid heart rate accompanied by fatigue? Thank you, doctor.
