Does slow heart rate require a pacemaker?

A slow heart rate, or bradycardia, may require a pacemaker if it causes symptoms such as dizziness, fatigue, or fainting, or if it leads to serious complications. The decision to implant a pacemaker depends on the underlying cause and severity of the bradycardia. If the heart rate is consistently low but not symptomatic, monitoring may be sufficient. Ultimately, a healthcare provider will assess the situation to determine the best course of action.
