Atrioventricular nodal block during atrial flutter ablation software#
Narayan and his team use the software and tools to pinpoint all the locations where arrhythmias begin.įIRM helps make cardiac ablation more accurate, which means people may not need repeat treatment to manage symptoms. One of our electrophysiologists, Sanjiv Narayan, MD, developed a mapping technology known as FIRM (focal impulse and rotor modulation). A challenge for doctors has been to quickly and accurately identify those areas, so that they can apply ablation treatment more precisely. In many people with persistent AFib, the irregular heart rhythms can also begin in other areas. Most arrhythmias begin in a few commonly known areas of the heart, such as where the pulmonary veins (veins bringing oxygen-rich blood from the lungs) enter the left atrium. In this procedure, our doctors access the outside of the heart using a catheter inserted through a small incision under the breastbone. Our doctors use epicardial ablation to treat tissue in the epicardium, a membrane surrounding the heart. Some types of arrhythmias originate on the outside of the heart and cannot be treated with standard catheter ablation. Learn more about cryoablation for arrhythmia. Wang, MD, co-invented cryoballoon ablation, which uses a special balloon catheter to treat advanced AFib. That makes this procedure particularly helpful for people who have arrhythmias that are close to other sensitive structures in the heart.Īt Stanford, our team has participated in research and clinical trials in catheter cryoablation since the beginning. Cryoablation causes less damage to surrounding tissue than some other types of ablation. In this catheter-based procedure, our doctors use extreme cold to freeze and destroy heart tissue to correct the arrhythmia. For this reason, we use this option only when no other treatment methods have been successful. Because AV node ablation permanently stops the electrical connection, you must have a pacemaker implanted to regulate your heartbeat. In this procedure, the doctor targets the AV node, a nerve that transmits electrical signals from the atria to the ventricles. AV node (or AV junction) ablation prevents the atria from controlling the pumping action of the lower chambers (ventricles). If you have AFib or another fast arrhythmia that involves the atria (upper chambers of the heart), medication may not be enough to manage the irregular heartbeat. Our goal is to improve your health by reducing your symptoms and controlling arrhythmias. Our arrhythmia team has extensive experience in advanced catheter ablation procedures to treat different types of arrhythmia and certain structural heart diseases.
