The maze procedure is a type of heart surgery used to fix a condition that involves an irregular heartbeat, known as atrial fibrillation. The surgical procedure involves creating scar tissue at strategic locations around the heart. This helps regulate the erratic electric impulses that contribute to...
The sinoatrial (SA) nodes are areas of the heart's atrium that act as the heart's pacemaker. Impulses from the SA node cause the heart’s chambers to contract. Purkinje fibers receive their impulses from the SA node and move the impulse through the heart’s muscles. Just below the atrium...
This creates scar tissue and prevents electrical signals that cause A-fib. You may need this procedure more than 1 time. Ask for more information on A-fib ablation. A pacemaker may be inserted into your heart. A pacemaker is a device that controls your heartbeat. A pacemaker may be ...
Use the bend of your arm if a tissue is not available. Then wash your hands well with soap and water or use a hand sanitizer. Do not stand close to anyone who is sneezing or coughing. Do not share items. Examples include eating utensils, drinks, and food. Ask about vaccines you may...
