the T wave, which indicates ventricular repolarization
The deflection waves in an ECG tracing include the P wave (atrial depolarization), QRS complex (ventricular depolarization), and T wave (ventricular repolarization). Each of these waves represents different electrical activity of the heart during a cardiac cycle.
The three types of deflection waves seen in a typical ECG are the P wave (atrial depolarization), the QRS complex (ventricular depolarization), and the T wave (ventricular repolarization). They represent the different electrical activities of the heart during each phase of the cardiac cycle.
The T wave is positive in an ECG due to the direction and charge. This positive deflection occurs after each QRS complex.
The "R" is the greatest deflection from the baseline on the ECG. The R is part of the QRS complex. This complex represents ventricular depolarization in the heart.

T waves on an ECG represent the repolarization of the ventricles of the heart, indicating the relaxation phase of the heart's electrical activity.
T waves in an electrocardiogram (ECG) represent the repolarization of the ventricles in the heart, indicating the recovery phase after contraction.
Q waves in the inferior leads on an ECG indicate previous myocardial infarction affecting the inferior wall of the heart. They represent an area of scar tissue where the electrical activity is disrupted, resulting in a negative deflection. The presence of pathological Q waves suggests permanent damage to the heart muscle in that region.
Two T waves on an ECG indicate that the heart's electrical activity is normal and functioning properly.
The absence of P or T waves on an ECG may indicate abnormalities such as atrial fibrillation, ventricular tachycardia, or electrolyte imbalances.
