A Wiggers diagram modified from [1]. A Wiggers diagram, named after its developer, Carl Wiggers, is a unique diagram that has been used in teaching cardiac physiology for more than a century.
Heart rate is the frequency of the heartbeat measured by the number of contractions of the heart per minute (beats per minute, or bpm). The heart rate varies according to the body's physical needs, including the need to absorb oxygen and excrete carbon dioxide.
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 ...
Heart sounds are the noises generated by the beating heart and the resultant flow of blood through it. Specifically, the sounds reflect the turbulence created when the heart valves snap shut. In cardiac auscultation , an examiner may use a stethoscope to listen for these unique and distinct sounds that provide important auditory data regarding ...

As the heart beats, these pulses are transmitted smoothly via laminar (non-turbulent) blood flow throughout the arteries, and no sound is produced. Similarly, if the cuff of a sphygmomanometer is placed around a patient's upper arm and inflated to a pressure above the patient's systolic blood pressure , there will be no sound audible.
A heart rate that is too fast – above 100 beats per minute in adults – is called tachycardia. A heart rate that is too slow – below 60 beats per minute – is called bradycardia. [43] Many types of arrhythmia present no symptoms. When symptoms are present, they may include palpitations, or feeling a pause between heartbeats.
Floyer created a watch that counted a user's heart beat for sixty seconds, it created an easier way to count and measure the heart rate of patients. Floyers' designs were physically made by Samuel Watson, who was involved in horology in the late seventeenth century. [4] Floyers' original designs of a pulse watch
