Bradycardia, also called bradyarrhythmia, is a resting heart rate under 60 beats per minute (BPM). [1] While bradycardia can result from various pathologic processes, it is commonly a physiologic response to cardiovascular conditioning or due to asymptomatic type 1 atrioventricular block.
Bradycardia: The heart rate decreases significantly when the face is exposed to cold water. This helps to conserve oxygen by slowing down the heartbeat. The degree of bradycardia can vary among individuals, but it is a common and well-documented response.
Bradycardia is the response to facial contact with cold water: the human heart rate slows down ten to twenty-five percent. [8] Seals experience changes that are even more dramatic, going from about 125 beats per minute to as low as 10 on an extended dive.
The ECG can detect sinus bradycardia, a resting heart rate of fewer than 60 beats per minute. This is often accompanied by sinus arrhythmia. The pulse of a person with athlete's heart can sometimes be irregular while at rest, but usually returns to normal after exercise begins. [12] [13] [14]
Depending on the intensity of the exercise, cooling down after a workout method, such as intense weightlifting, can involve a slow jog or walk. Cooling down allows the heart rate to return to its resting rate. Additionally cooling down may reduce dizziness for professional or serious athletes and vocal performers after strenuous workouts.

Heart rate recovery (HRR) is the reduction in heart rate at peak exercise and the rate as measured after a cool-down period of fixed duration. [56] A greater reduction in heart rate after exercise during the reference period is associated with a higher level of cardiac fitness. [57]
