In telemetry, what is the function of a defibrillator?

• A. To monitor blood pressure
• B. To deliver a dose of electric current to the heart
• C. To perform a stress test
• D. To give medication intravenously

Answer: (B)

In telemetry, a defibrillator serves a critical role by delivering a dose of electric current to the heart. This electrical shock is designed to restore a normal rhythm to the heart in cases of arrhythmias, such as ventricular fibrillation or pulseless ventricular tachycardia. When the heart is not beating effectively, the rapid delivery of an electric shock can depolarize the heart muscle and allow the natural pacemaker of the heart to regain control, potentially saving the life of the patient. Defibrillators are vital in emergency situations, especially in cases of cardiac arrest, where immediate intervention is necessary. This function distinguishes defibrillators from other medical devices and procedures like monitoring blood pressure, performing stress tests, or administering medication intravenously, which focus on different aspects of patient care and diagnostics.
