    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 ...

  3. Heart rate - Wikipedia

    en.wikipedia.org/wiki/Heart_rate

    The mortality rate of patients with myocardial infarction increased from 15% to 41% if their admission heart rate was greater than 90 beats per minute. [8] For endurance athletes at the elite level, it is not unusual to have a resting heart rate between 33 and 50 bpm. [citation needed]

    On average, though, the AHA says a resting heart rate of 60 to 100 beats per minute (bpm) is “normal” for most adults. ... occurs when your heart rate falls below 60 bpm.

    en.wikipedia.org/wiki/Vital_signs

    The pulse is the rate at which the heart beats while pumping blood through the arteries, recorded as beats per minute (bpm). [11] It may also be called "heart rate". In addition to providing the heart rate, the pulse should also be evaluated for strength and obvious rhythm abnormalities. [11] The pulse is commonly taken at the wrist (radial ...

  6. Sinus tachycardia - Wikipedia

    en.wikipedia.org/wiki/Sinus_tachycardia

    Sinus tachycardia is a sinus rhythm of the heart, with an increased rate of electrical discharge from the sinoatrial node, resulting in a tachycardia, a heart rate that is higher than the upper limit of normal (90-100 beats per minute for adult humans). [1] The normal resting heart rate is 60–90 bpm in an average adult. [2] Normal heart rates ...

  7. Cardiac output - Wikipedia

    en.wikipedia.org/wiki/Cardiac_output

    Major factors influencing cardiac output – heart rate and stroke volume, both of which are variable. [1]In cardiac physiology, cardiac output (CO), also known as heart output and often denoted by the symbols , ˙, or ˙, [2] is the volumetric flow rate of the heart's pumping output: that is, the volume of blood being pumped by a single ventricle of the heart, per unit time (usually measured ...

    The resting heart rate of a newborn can be 120 beats per minute (bpm) and this gradually decreases until maturity and then gradually increases again with age. The adult resting heart rate ranges from 60 to 100 bpm. Exercise and fitness levels, age and basal metabolic rate can all affect the heart rate. An athlete's heart rate can be lower than ...

  9. Sinus rhythm - Wikipedia

    en.wikipedia.org/wiki/Sinus_rhythm

    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.
