Pulmonary vein ablation, also called pulmonary vein antrum isolation or PVAI, is a treatment for atrial fibrillation (afib). Afib is the most common irregular heart rhythm. It starts in the atria, or the upper chambers of the heart. When afib occurs, many different electrical impulses rapidly fire at once. These impulses cause a very fast, … Read More
While most serious issues related to heart rhythm disturbances occur in the heart’s upper chambers, or atria, sometimes they do occur in the lower chambers, the ventricles, which are the main pumping chambers. This can cause a very rapid heartbeat called ventricular tachycardia. It’s usually caused by scarring from a heart attack or other issues … Read More
Sometimes the pathway in the heart’s electrical system is interrupted, which causes changes in heart rate and rhythm. A slow heartbeat can occur because the sinus node, the natural “battery” of the heart, is slow. Other times electrical conduction between the upper and lower chambers of the heart is disrupted. When this happens, the heart … Read More
We usually don’t notice the beating of our hearts unless something out of the ordinary occurs. Most people occasionally feel the sensation of extra heartbeats. While certain issues with your heart’s electrical system are concerning and serious, sometimes extra heartbeats aren’t clinically significant. Usually this occurs due to benign rhythm disturbances in the heart’s lower … Read More

How a DASH diet could help lower your blood pressure. Our expert explains.
Many medical dramas on TV or in the movies feature defibrillation or “shock” paddles when someone is in the midst of a cardiac arrest. Similarly, an implantable cardioverter defibrillator, or ICD, is an electronic device that constantly monitors your heart rhythm. It delivers energy to the heart muscle once it detects a very fast, abnormal … Read More
A heart block is a problem in the heart’s electrical system. Find out the different types and what types of issues they can cause.
Did you know that arrhythmias, or abnormally rapid heartbeats, can be present at birth? Watch as our expert explains.
Your heart’s electrical system is the power source that keeps your heart beating regularly. When something goes wrong with the heart’s “wiring,” you can develop an arrhythmia, which is an irregular or abnormal heartbeat. In this white board session, Walid Saliba, MD, Director of Cleveland Clinic’s Electrophysiology Lab, explains how a procedure called a catheter … Read More
Nearly 100 percent of arrhythmias, or irregular heartbeats, that occur take place in the atria, or the upper chambers of the heart. The most common ones that we hear about are atrial fibrillation and its cousin, atrial flutter. When this occurs, the heart’s electrical system misfires, causing the rapid firing of too many different impulses … Read More
