QRS duration: __________ QT duration: ____________
Ventricular rate and rhythm: _____________
Atrial rate rhythm: _____________________
PR interval: __________________________
Interpretation: ________________________
Introduction:
The electrocardiogram (ECG) is the graphical representation of a patient’s heart rate that records the electrical signals of the heart. It contains wave components, such as P, Q, R, S, T, and U, which are present in the wave. The ECG interpretation is done when a patient is in serious condition.
