four to 10 electrodes are located on the end of the catheters, which have the ability to send electrical signals to stimulate the heart (called pacing) and to receive electrical signals from the heart
electrodes are placed directly on heart tissue. This placement allows the electrophysiologist to determine the specific location of an arrhythmia and, often, to correct it during the same procedure
clot formation may occur and is minimized with anticoagulant medications administered during the procedure. Vascular injuries causing hemorrhage or thrombophlebitis are possible. Cardiac perforations are also possible.
The patient may be advised to stop taking certain medications, especially cardiac medications, that may interfere with the test results. The patient fasts for six to eight hours prior to the procedure
Electrophysiology is of Greek origin. It is the study of electrical properties of biological cells and tissue. It measures voltage change or electric currents on many scales like ion channel protein to organs like the heart.
Mine was billed at $18, 425 for the evaluation with additional charges of $4,704 for "intracardia electrophysiology" and $5,428 for "Stimulations, pacing of the heart." The insurance company has a contracted price for less than that, however.
Cardiovascular is related to heart functioning and various blood vessels. It relates to the heart and the various blood vessels, like arteries and veins. It can also be used to refer to cardiovascular (cardio) exercise. For more information about cardiovascular exercise, or how to do cardiovascular exercise for either health or fat loss, see the page link, further down this page, listed under Related Questions.
when the standard EKG, Holter monitor, event recorder, stress test , echocardiogram, or angiogram cannot provide enough information to evaluate an abnormal heart rhythm (arrhythmia).
The normal function of the heart depends on its electrical activity, and the effect of this activity on each of its cells. When a heart is diseased, impaired electrical activity is often the factor that leads to sudden death

A diagnostic procedure that involves removal of a small tissue sample for study is called
certain tachycardias (fast heartbeats) or bradycardias (slow heartbeats) of unknown cause; patients who have been resuscitated after experiencing sudden cardiac arrest; various symptoms of unknown cause
