Question

1. which of these procedures is used to deliver an electrical shock with the goal of restoring normal sinus rhythm (nsr)?

event recorder
pacemaker
defibrillation
stress test

Explanation:

• An event recorder is used to monitor heart activity over time, not to deliver an electrical shock.
• A pacemaker is a device that sends electrical impulses to regulate the heart's rhythm, but it doesn't deliver a shock to restore normal sinus rhythm.
• Defibrillation involves delivering an electrical shock to the heart to try to restore normal sinus rhythm, especially in cases of life - threatening arrhythmias.
• A stress test is used to assess how the heart responds to physical stress, not to deliver a shock.

Answer:

C. Defibrillation
