The beating heart
ОглавлениеFollowing vigorous exercise or when we are resting and quiet, most people become aware of the sensations and sounds of their beating heart. In young healthy adults, typical resting heart rates range from 60 to 80 beats per minute. In general the resting heart rate relates to the individual’s current level of physical fitness; indeed, some athletes may have resting heart rates in the 40s while those who are physically unfit tend to have higher rates.
There are many ways of measuring a patient’s heart rate including: taking their pulse, listening to the heart using a stethoscope or other device such as a Doppler probe or viewing the visual display on an electrocardiogram (ECG) machine.
