The ballistocardiograph (BCG) is a measure of ballistic forces generated by the heart. [1] The downward movement of blood through the descending aorta produces an upward recoil, moving the body upward with each heartbeat. [2] As different parts of the aorta expand and contract, the body continues to move downward and upward in a repeating ...
A heart rate monitor (HRM) is a personal monitoring device that allows one to measure/display heart rate in real time or record the heart rate for later study. It is largely used to gather heart rate data while performing various types of physical exercise. Measuring electrical heart information is referred to as electrocardiography (ECG or EKG).
Cardiac monitoring generally refers to continuous or intermittent monitoring of heart activity to assess a patient's condition relative to their cardiac rhythm.Cardiac monitoring is usually carried out using electrocardiography, which is a noninvasive process that records the heart's electrical activity and displays it in an electrocardiogram.

Floyer wanted to develop a watch to measure the accurate pulse rates of his patients. 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 ...
In a normal heart, the heart rate is the rate at which the sinoatrial node depolarizes since it is the source of depolarization of the heart. Heart rate, like other vital signs such as blood pressure and respiratory rate, change with age. In adults, a normal heart rate is between 60 and 100 bpm (normocardic), whereas it is higher in children. [57]
The Holter's most common use is for monitoring ECG heart activity (electrocardiography or ECG). Its extended recording period is sometimes useful for observing occasional cardiac arrhythmias which would be difficult to identify in a shorter period. For patients having more transient symptoms, a cardiac event monitor which can be worn for a ...
