WebThere are five main parts of the electrocardiogram or EKG. The P wave is a small wave which represents atrial depolarization. The T wave represents ventricular repolarization which is obscure by the QRS complex. The PR interval measures time between the initial P wave and the initial deflection of the QRS complex.

What does a negative deflection in the ECG indicate?

WebMaximal positive ECG deflection occurs in lead I when a wave of depolarization travels parallel to the axis from the right to left arm. If a wave of depolarization heads away from the left arm, the deflection is negative. Also, by these rules, a wave of repolarization moving away from the left arm is recorded as a positive deflection. Similar ... WebFeb 1, 2024 · When electrical impulse travels towards or away from an ECG lead, a deflection from the baseline is recorded on the ECG strip, that is called a wave.
