Question

Quizplus · Accepted Answer

An electronic pacemaker is specifically indicated for symptomatic bradycardia, which is defined as a heart rate less than 60 beats per minute and associated symptoms such as dizziness, lightheadedness, and syncope. Sinus tachycardia is a normal response to physiological stressors and does not require intervention. First-degree heart block is a mild conduction abnormality that does not typically require treatment. Ventricular fibrillation is a life-threatening arrhythmia that requires immediate defibrillation, not a pacemaker.
