According to the research, the p wave on an electrocardiogram (ecg) represents the first wave of the cardiac cycle which is the atrial electrical depolarization.
<h3>What is an electrocardiogram?</h3>
It is the graph that records the electrical activity of the heart and allows the diagnosis of different cardiovascular diseases and helps to know the state of the heart muscle.
It presents a P wave (corresponding to atrial depolarization), a QRS complex (ventricular depolarization), and a T wave (ventricular repolarization).
Therefore, we can conclude that according to the research, the p wave on an electrocardiogram (ecg) represents the first wave of the cardiac cycle which is the atrial electrical depolarization.
