As a medical professional with expertise in cardiology, I can provide you with an explanation of what a wandering pacemaker is. A wandering pacemaker is a type of arrhythmia, which is an irregularity in the heart's rhythm. Normally, the heart's rhythm is controlled by the sinoatrial node (SA node), which is the heart's natural pacemaker located in the right atrium. However, in the case of a wandering pacemaker, the control of the heart's rhythm shifts around, or "wanders," between the SA node, the atria (the upper chambers of the heart), and/or the atrioventricular node (AV node), which is another pacemaker site located in the lower part of the heart. This wandering can result in a heart rate that is either too fast (tachycardia) or too slow (bradycardia), and it can vary in regularity. The condition is often benign and may not require treatment, but in some cases, it can be a sign of an underlying heart condition that needs medical attention. read more >>
