Electrocardiography is the process of producing an electrocardiogram (ECG or EKG [a]), a recording of the heart's electrical activity through repeated cardiac cycles. [4] It is an electrogram of the heart which is a graph of voltage versus time of the electrical activity of the heart [ 5 ] using electrodes placed on the skin.
Cardiac physiology or heart function is the study of healthy, unimpaired function of the heart: involving blood flow; myocardium structure; the electrical conduction system of the heart; the cardiac cycle and cardiac output and how these interact and depend on one another.
Loop recorders is an implanted ECG recorders for long-term monitoring of ECG to allow for diagnosis of an arrhythmia Left atrial appendage occlusion devices Additionally, there are, at times, indications to remove these devices and extraction (ie, removal) of these devices can also be performed by electrophysiologists.
During an interview with CNBC yesterday, Apple CEO Tim Cook said that Apple's biggest contribution to the world will ultimately be in the realm of healthcare. "If you zoom out into the future, and ...
An advanced life support paramedic unit of Palm Beach County Fire-Rescue used for EMS in Palm Beach County, Florida.. Advanced Life Support (ALS) is a set of life saving protocols and skills that extend basic life support to further support the circulation and provide an open airway and adequate ventilation (breathing).
Unlike standard basal ECG recording, which requires only a few seconds, SAECG recording requires a few minutes (usually about 7-10 minutes), as the machine must record multiple subsequent QRS potentials to remove interference due to skeletal muscle and to obtain a statistically significant average trace. For this reason, it is important for the ...

A cardiac stress test is a cardiological examination that evaluates the cardiovascular system's response to external stress within a controlled clinical setting. This stress response can be induced through physical exercise (usually a treadmill) or intravenous pharmacological stimulation of heart rate.
