you will often feel your heart racing. This rapid, abnormal heart rate can be dangerous if not treated and controlled quickly. With AFib, heart rate is so fast and irregular, blood may not be pumped adequately
That loop shape allows for single-shot ablation, which is the delivery of energy across multiple parts of the pulmonary vein for a procedure that can be simpler and faster. That tissue-selective energy kills cardiac myocytes to block irregular heart signals that cause AFib, but spares phren...
“A premature ventricular contraction (PVC) is a relatively common event where the heartbeat is initiated by Purkinje fibers in the ventricles rather than by the sinoatrial node, the normal heartbeat initiator. The electrical events of the heart detected by the electrocardiogram (ECG) allow a PVC...
