In the Copenhagen City Heart Study a heart rate of 65 bpm rather than 80 bpm was associated with 4.6 years longer life expectancy in men and 3.6 years in women. [27] Other studies have shown all-cause mortality is increased by 1.22 (hazard ratio) when heart rate exceeds 90 beats per minute. [ 7 ]
A pulse watch, also known as a pulsometer or pulsograph, [1] is an individual monitoring and measuring device with the ability to measure heart or pulse rate.Detection can occur in real time or can be saved and stored for later review.
Postural orthostatic tachycardia syndrome (POTS) is a condition characterized by an abnormally large increase in heart rate upon sitting up or standing. [1] POTS is a disorder of the autonomic nervous system that can lead to a variety of symptoms, [10] including lightheadedness, brain fog, blurred vision, weakness, fatigue, headaches, heart palpitations, exercise intolerance, nausea ...
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]
Bradycardia, also called bradyarrhythmia, is a resting heart rate under 60 beats per minute (BPM). [1] While bradycardia can result from various pathological processes, it is commonly a physiological response to cardiovascular conditioning or due to asymptomatic type 1 atrioventricular block.

Respiratory system Heart rate and pulse and systolic and diastolic blood pressure measurements and the level of oxygen saturation - some other vital signs - can provide related information about the heart and lungs and the great vessels, since these systems work with one another, are relatively close together in gross (macroscopic) anatomy, and ...
Further down the electrical conducting system of the heart is the Bundle of His. The left and right bundle branches, and the Purkinje fibers, will also produce a spontaneous action potential at a rate of 30–40 beats per minute, so if the SA and AV node both fail to function, these cells can become pacemakers. These cells will be initiating ...
