Bradycardia is a condition in which an individual has a slow heart rate, which would need further workup. Bradycardia is typically defined as a resting heart rate of fewer than 60 beats per minute in adults, although it may be a normal finding in certain individuals such as athletes and other active adults. It can result from various factors, including certain medications, heart-related issues, or an overactive vagus nerve. Severe bradycardia may lead to symptoms like dizziness, fainting, and fatigue.
