  2. Heart rate - Wikipedia

    en.wikipedia.org/wiki/Heart_rate

    For healthy people, the Target Heart Rate (THR) or Training Heart Rate Range (THRR) is a desired range of heart rate reached during aerobic exercise which enables one's heart and lungs to receive the most benefit from a workout. This theoretical range varies based mostly on age; however, a person's physical condition, sex, and previous training ...

    en.wikipedia.org/wiki/Bradycardia

    Bradycardia, also called bradyarrhythmia, is a resting heart rate under 60 beats per minute (BPM). [1] While bradycardia can result from various pathologic processes, it is commonly a physiologic response to cardiovascular conditioning or due to asymptomatic type 1 atrioventricular block.

    The pulse may vary due to exercise, fitness level, disease, emotions, and medications. [11] The pulse also varies with age. A newborn can have a heart rate of 100–⁠160 bpm, an infant (0–⁠5 months old) a heart rate of 90–⁠150 bpm, and a toddler (6–⁠12 months old) a heart rate of 80–140 bpm. [12]

  5. Sinus arrhythmia - Wikipedia

    en.wikipedia.org/wiki/Sinus_arrhythmia

    During respiration, the intermittent vagus nerve activation occurs, which results in beat to beat variations in the resting heart rate. During inspiration vagal tone is slowed down and the heart rate goes up (being maximal at the peak of inspiration), while during expiration vagal tone is increased and heart rate decreases, being slowest at end-expiration.

  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]

    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 ...
