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
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
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
Your heart’s electrical system spreads impulses through the upper chambers like a wave and then down to the lower chambers through an electrical bridge. Sometimes, something called a “heart block” can occur. This means an abnormality in the electrical bridge between the upper and lower chambers occurs that prevents impulses from the upper chambers from … Read More
The heart’s electrical system conducts electrical impulses between the upper and lower chamber to keep the heart beating regularly and pump blood through our bodies. However, as with any electrical system, sometimes things don’t work exactly as they should. Occasionally a pathway that isn’t normally there is formed, which basically creates an electrical “short circuit” … Read More
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 and Co-Director of the Ventricular Arrhythmia Center, … Read More
