What Is The Correct Order Of Depolarization In The Heart? The atrial depolarization spreads to the atrioventricular (AV) node, passes through the bundle of His What is the order of the conduction system of the heart? The cardiac conduction system comprises the following structures, in order, the SA node, the AV node, the bundle of
What Does The QRS Complex On An ECG Represent? A combination of the Q wave, R wave and S wave, the “QRS complex” represents ventricular depolarization. This term can be confusing, as not all ECG leads contain all three of these waves; yet a “QRS complex” is said to be present regardless. What is the
How Is A Cardiac Cycle Represented On An Ecg Tracing? A typical ECG tracing of the cardiac cycle (heartbeat) consists of a P wave (atrial depolarization ), a QRS complex (ventricular depolarization), and a T wave (ventricular repolarization). An additional wave, the U wave ( Purkinje repolarization), is often visible, but not always. What do
