heart diseaseepidemiologyResting heart rate (RHR) is a clinical parameter easily measurable with typical value between 50聽and聽90 beats per minute (bpm) that varies during the day with a night-time decrease.1 RHR can go down to 30 bpm in those with good physical condition, but RHR is ...
Getting fitter can lower one's heart rate, by making the heart muscles work more efficiently. A well-trained athlete may have a resting heart rate of 40 to 60 bpm, according to theAmerican Heart Association(AHA). At the height of his career, cyclist Miguel Indurain reportedly had a restin...
Anotherresearchstudy found that the average heart rate during sleep of 10 female subjects was 65 bpm, 63 bpm, and 67 bpm, depending on training status. Heart rate while sleeping varied by about 8 beats per minute between individuals. However, as with heart rate during exercise and average re...
At rest, the sinoatrial rate, and therefore the heart rate when the heart is in sinus rhythm (i.e., controlled by the SA node), is usually 60-80 beats/minutes (bpm), which is well below the intrinsic firing rate. This reduced resting rate is due to vagal tone. Efferent vagus nerve...
