Summary Introduction
To review:
The given blank space in the statement using the following ECG graph.
QRS duration: __________ QT duration: ____________
Ventricular rate and rhythm: _____________
Atrial rate rhythm: _____________________
PR interval: __________________________
Interpretation: ________________________
Introduction:
The process by which the heart rate of a patient is recorded is known as electrocardiography (ECG). The representation of this heart rate in a graph is called electrocardiogram. The electrical changes in the heart are detected by electrodes that are placed on the skin. The graph shows various components, such as P, Q, R, S, T, and U. These graphs are seen by doctors who interpret them in a systemic approach.
