The process of the gradual decline towards a preexercise value after intense exercise is the result of a coordinated interaction between the sympathetic and parasympathetic systems.
Sympathetic withdrawal and parasympathetic reactivation occur shortly after cessation of physical activity.
A low HRR is a marker of autonomic dysfunction and as a tool to assess risk for morbidity derived from this disequilibrium.
Mortality risk of an abnormal heat rate recovery is comparable to having angiographic evidence of severe coronary artery disease.
An independent predictor of death.
As a general rule, a lower recovery heart rate following vigorous exercise is better.
The heart rate should fall under 100 beats per minute in the first three minutes after exercise.
The heart rate drops most sharply in the first minute after you stop exercising; it should then fall about 20 beats a minute, and a drop of less than 12 beats a minute is considered abnormal.
Low HRR associated with sudden cardiac death.
Abnormal heart rate recovery adversely affects mortality and is independent of ischemic burden.
Drop in heart rate after exercising reflects withdrawal of the sympathetic nervous system and reactivation of the parasympathetic nervous system.
A marker of autonomic dysfunction and an independent predictor of the risk of all-cause mortality, sudden cardiac death, and cardiovascular events.
Slower heart rate recovery is associated with diastolic dysfunction, reduced left ventricular ejection fraction, and increased left ventricular mass in patients with heart failure.
Cardiac rehabilitation improves heart rate recovery.
Heart rate recovery is significantly different between men and women only in age group 50-59 years.
Lower heart rate recovery is independently associated with the onset of atrial fibrillation doing long-term follow-up in middle-aged adults.
Can predict the development of malignant arrhythmias after myocardial infarction or in patients ref2242ed for the evaluation of chest pain.
Can predict emergence of new one set heart failure or atrial fibrillation in patients with diabetes mellitus.
