Bradycardia is defined as a slow heart rate, typically characterized by a rate of fewer than 60 beats per minute. This condition can occur during sleep, in trained athletes, or as a result of certain medical conditions. Understanding the normal ranges for heart rates is crucial; typically, a resting heart rate for adults falls between 60 to 100 beats per minute, which is why a heart rate below this threshold is classified as bradycardia. This distinction is important for identifying potential health concerns in patients, as bradycardia can lead to insufficient blood flow to the organs and tissues if severe or symptomatic.
