Bradycardia意思

"Bradycardia" is a medical term that refers to a slow heart rate. In humans, bradycardia is generally defined as a resting heart rate of fewer than 60 beats per minute (bpm) in adults. The normal resting heart rate for adults is typically between 60 and 100 bpm, but this can vary depending on factors such as age, physical activity level, and overall health.

Bradycardia can be a normal finding in some individuals, particularly athletes or people in good physical condition, as their hearts can pump more blood with each beat, allowing for a slower heart rate. However, bradycardia can also be a sign of an underlying medical condition, such as heart disease, thyroid problems, or certain medications. In some cases, bradycardia can be a serious condition that requires medical attention.
