Quizplus · Accepted Answer

A pacemaker may be required for sinus bradycardia, which is a slow heart rate that can cause symptoms such as dizziness, fainting, and shortness of breath. Sinus tachycardia is a fast heart rate that may not require a pacemaker. Ventricular fibrillation is a life-threatening heart rhythm that requires immediate medical attention with interventions such as defibrillation. Heart failure is a condition where the heart is unable to pump effectively, and while some patients with heart failure may benefit from a pacemaker, it is not always required.
