Bradycardia is defined as:

Bradycardia is defined as an abnormally slow heart rate, typically characterized by a heart rate of less than 60 beats per minute in adults. This condition can occur due to various factors, including increased vagal tone, certain medications, or underlying health issues affecting the heart's electrical system. Recognizing bradycardia is essential for paramedics and other healthcare providers, as it may necessitate further evaluation and intervention, especially if the patient is symptomatic.

Understanding the significance of bradycardia within the context of the overall heart rate spectrum is important for assessing a patient's cardiovascular health. An abnormally slow heart rate can lead to inadequate blood flow and, therefore, could be life-threatening if not addressed promptly.
