Introduction:

The process named electrocardiography (ECG) is used to monitor a patient’s heart rate. It records the electric signals that are produced by the heart in the form of wave components, such as P, Q, R, S, T, and U. The electric signals are recorded by 10 electrodes that are placed over the patient’s body.

Explanation

First-degree atrioventricular block (AV block) is also called first-degree heart block. The conduction of signals from atria to ventricle through AV nodes is at a slower rate. It is caused due to the long PR interval. It is common in a young person and can cause coronary heart diseases. It can be treated through medicines.

QRS duration: QRS duration is less than 0.12 seconds.

QT duration: It is more than 0.12 seconds.

Ventricular rate and rhythm: The ventricular rate is between 60 and 100 bpm...
