WebThe conduction system of the heart. Left: Normal excitation originates in the sinoatrial (SA) node then propagates through both atria. The atrial depolarization spreads to the atrioventricular (AV) node, and passes through the bundle of His to the bundle branches/Purkinje fibers. Right: The table shows conduction velocities and intrinsic ... WebThe bundle of His divides into right and left pathways, called bundle branches, to stimulate the right and left ventricles. Normally at rest, as the electrical impulse moves through the heart, the heart contracts about 60 …

WebJun 11, 2024 · Tests that can be used to diagnose a bundle branch block or its causes include: Electrocardiogram (ECG or EKG). This quick and painless test measures the electrical activity of the heart. During an ECG, sensors (electrodes) are attached to the chest and sometimes to the arms or legs. An ECG can show how well the heart is beating. the clever shepherd
