Why a Pulse Rate Rises

A pulse rate measures the number of times a heart beats in one minute. The rate can be determined by firmly placing two fingers on the side of the neck, inside the crook of the elbow or the wrist. Count the number of beats in 60 seconds. A normal range is between 60 and 100 beats per minute. A high rate may be caused by a number of physical, psychological or chemical factors.

Physical Factors.

• Your heart rate may increase during pregnancy.

  Pregnancy can cause a rise in the pulse rate as the heart struggles to provide for the increased demands of the mother and the fetus. Pain, fever and an overactive thyroid may also be associated with a rapid pulse. A weak and rapid pulse, along with low blood pressure, along with an altered mental state are symptoms of shock. The rate will often rise after heavy exercise or exertion.

Psychological Factors

• Stress may increase your heart rate.

  An increased heart rate may be a side effect of stress or anxiety. People with anxiety disorders may also experience a rapid pulse.

External Factors

• A cup of coffee can quicken your pulse.

  Caffeinated coffee is a stimulant which can increase pulse rate. Excessive alcohol use and smoking are linked to a rapid pulse. Medications and street drugs may also cause a jump in your heart rate.

When to see your Doctor

• Your doctor can rule out serous conditions associated with a fast pulse rate.

  Chances are, a rapid heartbeat will return to normal in time or with some lifestyle changes. However, it may indicate a condition known as tachycardia in which the heart may race up to 400 beats per minute. Your physician may order tests such as an electrocardiogram or an electrophysiology study.
