Tachycardia, also called tachyarrhythmia, is a heart rate that exceeds the normal resting rate. [1] In general, a resting heart rate over 100 beats per minute is accepted as tachycardia in adults. [1] Heart rates above the resting rate may be normal (such as with exercise) or abnormal (such as with electrical problems within the heart).
Specifically, a resting heart rate above 65 beats per minute has been shown to have a strong independent effect on premature mortality; every 10 beats per minute increase in resting heart rate has been shown to be associated with a 10–20% increase in risk of death. [79]
Resting heart rate isn’t a one-size-fits-all metric. In addition to age, factors including stress, hormones, anxiety, medication, and physical activity contribute to what may be considered a ...
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]
[table-of-contents] stripped. Whether brought on by stress, physical activity, or an extra cup of joe in the morning, most of us have all felt our heart rate quicken at one time or another.However ...
A resting heart rate that is too fast – above 100 beats per minute in adults – is called tachycardia, and a resting heart rate that is too slow – below 60 beats per minute – is called bradycardia. [2] Some types of arrhythmias have no symptoms. [1] Symptoms, when present, may include palpitations or feeling a pause between heartbeats. [1]
