Normal heart rate (classically 60 to 100 beats per minute for an adult). Regular rhythm, with less than 0.16-second variation in the shortest and longest durations between successive P waves; The sinus node should pace the heart – therefore, P waves must be round, all the same shape, and present before every QRS complex in a ratio of 1:1.

The normal range has since been revised in textbooks to 50–90 bpm for a human at total rest. Setting a lower threshold for bradycardia prevents misclassification of fit individuals as having a pathologic heart rate. The normal heart rate number can vary as children and adolescents tend to have faster heart rates than average adults.
What’s a normal heart rate? A “normal heart rate” for adults ranges from 60-100 beats per minute (bpm), says Brett Victor, M.D., F.A.C.C., cardiologist at Cardiology Consultants of ...
There are 6 different sinus arrhythmia. [1] [2]A normal heart should have a normal sinus rhythm, this rhythm can be identified by a ventricular rate of 60-100 bpm, at a regular rate, with a normal PR interval (0.12 to 0.20 second) and a normal QRS complex (0.12 second and less).
From Our Partners: Your heart rate can be an important indicator of your overall health. As you grow older, it becomes more difficult to know what is “normal” and what is not.
Those are times to seek out help because it may not be a reflection of your resting heart rate, but an abnormal heart rhythm that should get evaluated.” Having a pulse over 100 bpm is called ...
In a normal heart, the heart rate is the rate at which the sinoatrial node depolarizes since it is the source of depolarization of the heart. Heart rate, like other vital signs such as blood pressure and respiratory rate, change with age. In adults, a normal heart rate is between 60 and 100 bpm (normocardic), whereas it is higher in children ...
