Heart block is a disruption in the electrical signals that control your heart. Your heart depends on a steady flow of electrical signals that start in the heart’s upper chambers (atria). The signals ...

Second-degree heart block is a potentially serious but treatable condition affecting the heart’s electrical system. Treatment may require a pacemaker to stabilize the heart’s rhythm. Electrical ...

First-degree ventricular (heart) block affects the electrical signal that makes the heart beat. It causes a delay in a portion of the heart beat and may lead to a slow heart beat. Healthcare ...

Heart blockage, also known as coronary artery disease, occurs when plaque buildup narrows heart arteries, leading to symptoms like chest pain and potentially severe complications, and can range in ...

People with third degree heart block have an irregular heartbeat due to a total blockage of the electrical impulses that control the heart’s activity. It can lead to faintness and breathing difficulty ...

Impulses, or electrical signals, travel through both the left and right chambers of your heart to make it pump. But if the pathway is blocked, the impulses may move slower than normal or irregularly.

Dear Dr. Roach: Is COVID-19 infection a cause of heart block? I recently had a complete heart block, tested positive in the ER for COVID-19 (symptomless and post-vaccine), and was fitted with a ...
