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.

Explanation

Atrial fibrillation is caused due to a large number of PAC. The heartâ€™s upper chamber atria show abnormal heart rate causing irregular electrical signals in the heart. This condition can cause heart diseases like stroke and cardiac arrest.

QRS duration: The duration of the QRS complex is less than 0.12 seconds.

QT duration: The QT duration cannot be calculated as it is not regular throughout the graph.

Ventricular rate and rhythm: Ventricular rate is up to 150 bpm per minute...
