Mild Heart Block

Overview of Mild Heart Block

Mild heart block is a condition where electrical signals that control the rhythm of a person’s heart are delayed or blocked. It can cause problems with blood flow throughout the body, and can increase the risk of heart attack or stroke. It is a type of arrhythmia, which is an abnormal heart rhythm.

Mild heart block usually does not cause any symptoms, although it can cause some issues related to weaker heart muscle such as chest pain, weakness, shortness of breath, or fatigue. Usually, mild heart block can be managed successfully through lifestyle changes, medications, or medical devices.

Causes

The exact cause of mild heart block is not always known, but some common underlying causes include:

  • Aging or certain diseases that affect the nerves of the heart
  • Prior heart attack
  • Damage to the valves of the heart
  • High blood pressure
  • Scarring of the heart muscle after inflammation of the heart

Diagnosis

Mild heart block can be identified by a physical exam and electrocardiogram (ECG) test. An ECG is a test that measures the electrical signals that control the rhythm of a person’s heart. If mild heart block is suspected, a doctor may order other tests such as an echocardiogram or a Holter monitor to confirm the diagnosis.

Treatment

The treatment for mild heart block depends on the underlying cause and severity of the condition. Mild heart block can often be managed with lifestyle changes such as eating a healthy diet, exercising regularly, and avoiding tobacco products. In more severe cases, medications or medical devices such as a pacemaker may be needed to help regulate the rhythm of the heart.
