Tachycardia

Friday, January 02, 2015

Tachycardia is caused by something that disrupts the normal electrical impulses that control the rate of your hearts pumping action. Dr. Edward Hill takes a closer look at this condition in todays 60 Second Housecall.

Dr. Hill:

Tachycardia is a faster than normal heart rate at rest. A healthy adult heart normally beats 60 to 100 times a minute when a person is at rest. If you have tachycardia, the heart rate in the upper chambers or lower chambers of the heart, or both, is increased.

Heart rate is controlled by electrical signals sent across heart tissues. Tachycardia occurs when an abnormality in the heart produces rapid electrical signals.

When your hearts rate is too rapid, it may not effectively pump blood to the rest of your body, depriving your organs and tissues of oxygen. This can cause these tachycardia-related signs and symptoms:

Dizziness

Shortness of breath

Lightheadedness

Rapid pulse rate

Heart palpitations

Chest pain, or

Fainting

Some people with tachycardia have no symptoms, and the condition is only discovered during a physical examination or with a heart-monitoring test called an electrocardiogram.

A number of conditions can cause a rapid heart rate and tachycardia symptoms. Its important to get a prompt, accurate diagnosis and appropriate care.
