In 101 people free of heart disease during 24 hours Holter monitoring, 39 had at least 1 PVC, and 4 at least 100. Heart disease was excluded after physical examination, chest x-ray, ECG , echocardiography , maximal exercise stress test , right- and left-heart catheterization and coronary angiography . [ 30 ]
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).
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.

While studying PVC characteristics, Schmidt and his colleagues noticed that heart rate seemed to speed up after a PVC. To clarify, they listed the time from one heartbeat's R-wave to the next R-wave (called RR intervals) and synchronized these lists to the time of the PVC beat and averaged the values in the list. A plot of this averaged RR ...

Rhythm interpretation is an important part of healthcare in Emergency Medical Services . Trained medical personnel can determine different treatment options based on the cardiac rhythm of a patient. There are many common heart rhythms that are part of a few different categories, sinus arrhythmia, atrial arrhythmia, ventricular arrhythmia.

Digoxin: Helps slow the heart rate by blocking the number of electrical impulses that pass through the AV node into the lower heart chambers (ventricles). E lectrocardioversion: A procedure in which electric currents are used to reset the heart's rhythm back to regular pattern.
