Heart Rate Recovery after Submaximal Exercise Testing as a Predictor of Mortality in a Cardiovascularly Healthy Cohort
Article Abstract:
An abnormal heart rate recovery after exercise appears to be a risk factor for death even in people without heart disease. In most people, exercise makes the heart beat faster but the heart returns to normal after the exercise is over. In a study of 5,234 people with no evidence of heart disease, 312 died over a 12-year period. An abnormal heart rate recovery increased the risk of death about 55% even after allowing for level of fitness and other risk factors for cardiovascular disease.

Heart Rate Recovery and Treadmill Exercise Score as Predictors of Mortality in Patients Referred for Exercise ECG
Article Abstract:
Abnormal heart rate recovery after exercise and an intermediate- to high-risk treadmill exercise score are risk factors for death from heart disease, according to a study of 9,454 patients. Abnormal heart rate recovery means the heart does not return to a normal heart rate quickly after exercise.

Heart-rate recovery immediately after exercise as a predictor or mortality
Article Abstract:
A slower than normal decrease in heart rate after exercise appears to predict an increased risk of death. Normally, heart rate increases during exercise and then falls back down to the normal rate when people stop exercising. The decreasing heart rate following exercise is caused by the vagus nerve. A slower than normal decrease may indicate decreased activity of this nerve. In a study of 2,428 people followed for six years, people with a slower than normal decrease in heart rate after exercise had four times the risk of death.
