Heart Blockage: Symptoms, Types & Treatment
Heart Blockage: Symptoms, Types & Treatment Heart block, also known as atrioventricular block or conduction disorder, occurs when there is a disruption in the heart's electrical system, which controls the heartbeat and rhythm. This condition is characterized by impaired transmission of electrical signals between the upper and lower chambers of the heart. There are three types of heart block: first, second, and third degree, each varying in the extent of signal impairment. Types of Heart Block: First-degree heart block: Signals reach the ventricles, but at a slower rate, causing a delay in impulses. This is a milder form of heart block. Second-degree heart block: Divided into Type I and Type II conditions. Type I involves a gradual slowing of electrical impulses, leading to skipped beats. Type II results in occasional failure of impulses to reach the ventricles, causing an irregular and slow heartbeat. Third-degree heart block: Complete blockage of electrical signals from t...
