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).
AliveCor is a medical device and AI company that develops ECG hardware and software compatible with consumer mobile devices to enable remote heart rhythm monitoring and detection of abnormal heart rhythms, or arrhythmias. [4] [5] AliveCor was founded in 2011 and is headquartered in Mountain View, California, the United States.
Hence, the P-R interval after the PVC is longer than the baseline P-R interval. [ citation needed ] Concealed conduction can be seen in cardiac aberrancy when a bundle branch temporarily blocks due to being refractory, and conduction from the other bundle branch conceals into the blocked branch retrograde thus perpetuation the bundle branch ...
Monitoring of the heart rate can be performed as part of electrocardiography, but it can also be measured conveniently with specific heart rate monitors. Such heart rate monitors are largely used by performers of various types of physical exercise. A generic cardiac monitor has the following functions: A display of heart rate and heart rhythm
Ectopic beat is a disturbance of the cardiac rhythm frequently related to the electrical conduction system of the heart, in which beats arise from fibers or group of fibers outside the region in the heart muscle ordinarily responsible for impulse formation (i.e., the sinoatrial node).
For patients with more than 1,000 PVCs per day, the risk of developing left ventricular systolic dysfunction after 5 years follow-up is low. Frequent PVCs may increase the risk of developing cardiomyopathy, which can greatly impair heart function. A PVC burden greater than 10% is the minimal threshold for development of PVC-induced cardiomyopathy.

Heart rate turbulence (HRT) is a baroreflex-mediated adjustment of heart rate which acts as a counter-mechanism to premature ventricular contraction (PVC). [1] It consists of a brief speed-up in heart rate, followed by a slow decrease back to the baseline rate.
