I have a pulse rate usually of 79 or higher and blood pressure of
108/62. I exercise regulary. (Running) WHy is my pulse so high? Is there a potential problem?

Very good blood pressure. A resting pulse rate over 83 can predict greater risk, see below. Your pulse rate of 79 is getting close. Have you been sick? I'd suggest calling the Dr. Mirkin radio show available online at www.drmirkin.com

"FAST HEART RATE INCREASES RISK FOR HEART ATTACK

Gabe Mirkin, M.D.

Having a fast resting heart rate increases your risk for suffering a heart attack (1,6) and dying early (7).

Everything that you do, thinking, eating and moving speeds up your heart. So to know your resting heart rate, check it when you first wake in the morning. Place your fingers on the side of your neck where you feel a strong heart beat. Count your heart rate. If it beats more than 83 times a minute, you are three times more likely to suffer a heart attack in the next three years.

The test is dependable only if you are not sick, not under unusual stress and have not been working excessively hard for the last few days. A high heart rate increases is associated with higher blood pressures that damages arteries and forms plaques (5). A fast heart rate can knock plaques from arteries to block blood flow and cause heart attacks (3). If your resting heart rate is greater than 83, check with your doctor. "
