Drawing of the ECG, with labels of intervals. Cardiac electrophysiology is a branch of cardiology and basic science focusing on the electrical activities of the heart.The term is usually used in clinical context, to describe studies of such phenomena by invasive (intracardiac) catheter recording of spontaneous activity as well as of cardiac responses to programmed electrical stimulation ...
These side effects are similar to those that occur with other electrical stimulation therapies, such as pacemakers, CRT devices or ICD devices. [30] Furthermore, recorded complications did not differ between patients with activated or deactivated cardiac contractility modulation devices. [17]
The electrical system of the heart is centered on the periodic contraction (squeezing) of the muscle cells that is caused by the cardiac pacemaker located in the sinoatrial node. The study of the electrical aspects is a sub-field of electrophysiology called cardiac electrophysiology and is
A cardiac electrophysiology study (EP test or EP study) is a minimally invasive procedure using catheters introduced through a vein or artery to record electrical activity from within the heart. [1] This electrical activity is recorded when the heart is in a normal rhythm (sinus rhythm) to assess the conduction system of the heart and to look ...
Electrophysiologists are trained in the mechanism, function, and performance of the electrical activities of the heart. Cardiogeriatrics (geriatric cardiology) –Cardiogeriatrics, or geriatric cardiology, is the branch of cardiology and geriatric medicine that deals with the cardiovascular disorders in elderly people.
The electrical stimulation used in HWT differs from other forms of electrical stimulation such as TENS in terms of its waveform; it is intended to emulate the H waveform found in nerve signals, thus permitting the machine to use less power while attaining greater and deeper penetration of its low-frequency current.
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.
This stress response can be induced through physical exercise (usually a treadmill) or intravenous pharmacological stimulation of heart rate. [1] As the heart works progressively harder (stressed) it is monitored using an electrocardiogram (ECG) monitor. This measures the heart's electrical rhythms and broader electrophysiology. Pulse rate ...
