Is a low heart rate during sleep normal?

I am looking for clear information about slow heart rate. Is a low heart rate during sleep normal?

Is a low heart rate during sleep normal is a common cardiology question. The answer depends on your age, symptoms, medical history, medicines and overall cardiovascular risk. In general, slow heart rate should be interpreted in context rather than from one symptom, reading or test result alone. For heart disease prevention, the most useful measures are usually regular physical activity appropriate for your health, a diet rich in vegetables, fruits, whole grains, legumes and nuts, limiting excess salt, added sugar and highly processed foods, avoiding tobacco, maintaining a healthy weight, sleeping adequately and controlling blood pressure, cholesterol and diabetes. People with established heart disease should ask their doctor whether they need specific exercise, salt or fluid limits. Arrange medical review if symptoms are new, recurrent, worsening, occur with exercise, or are associated with fainting, significant breathlessness or chest discomfort. For people searching for information about slow heart rate, heart health, cardiology symptoms, heart disease prevention and cardiac tests, the safest approach is an individualized assessment rather than self-diagnosis from internet information.
