To review:
The given blank space in the statement using the following ECG graph.
QR QRS duration: __________ QT duration: ____________
Ventricular rate and rhythm: _____________
Atrial rate rhythm: _____________________
PR interval: __________________________
Interpretation: ________________________
Introduction:
Electrocardiogram (ECG) is a machine which monitors the heart rate of the patients. The electrical signals that are produced by the heartbeat are recorded in the form of wave components, such as P, Q, R, S, T, and U. Doctors through systemic approach interpret the ECG.
