heart block

Heart block is a condition where the electrical signals that control the heartbeat are delayed or blocked as they move through the heart’s electrical system. This can cause the heart to beat too slowly or irregularly. Depending on the severity, some people may experience symptoms like dizziness or fatigue, while others have no symptoms at all. Heart block can result from aging, heart disease, or damage to the electrical pathways. Treatment varies from monitoring to medical devices like pacemakers that help maintain a proper heart rhythm.
