Bradycardia is characterized by a heart rate that is:

Bradycardia is defined as a condition where the heart rate is significantly slower than the normal resting heart rate. A typical adult resting heart rate ranges from 60 to 100 beats per minute. Therefore, any heart rate that falls below 60 beats per minute is classified as bradycardia.

This condition can occur due to various physiological factors, including increased vagal tone, certain medications, or underlying health issues such as heart block or myocardial infarction. In clinical practice, understanding bradycardia is essential because it may present symptoms such as dizziness, fatigue, or, in severe cases, lead to more serious complications if not addressed. The distinction between heart rate categories is critical for diagnosing and managing various cardiovascular conditions effectively.
