Running Head: PREMATURE VENTRICULAR CONTRACTION Premature Ventricular Contraction [Writer Name] [Institute Name] Premature Ventricular Contraction Introduction Premature Ventricular Contraction is premature stimulation of the heart that occurs under the influence of impulses originating from different parts of the conduction system of the ventricles. The source of ventricular arrhythmia in most cases the branching bundle of His and Purkinje fibers. Ventricular premature beats are the most common disorder of cardiac rhythm. Its frequency depends on the method of diagnosis and contingent surveyed. When you register 12-lead ECG at rest are determined by ventricular extra systoles in about 5% of healthy young adults, whereas the Holter ECG monitoring for 24 hours, the frequency is 50%, although most of them represented by single beats can be detected and complex forms (Abdulla, 2001, 131-136). Discussion The prevalence of ventricular arrhythmias significantly increased in the presence of organic heart disease, especially involving the defeat of ventricular myocardium, correlating with the degree of its dysfunction. Regardless of the presence or absence of pathology of the cardiovascular system frequency of this arrhythmia increases with age, also noted relationship of ventricular arrhythmias with time of day. The causes of ventricular arrhythmias Ventricular premature beats arise in the absence of organic heart disease, and in their presence. In the first case, it is often (but not necessarily!) is associated with stress, smoking, drinking coffee and alcohol, causing increased activity of sympathetic-adrenal system. However, a significant part of healthy individuals extra systoles occur for no apparent reason. Although ventricular premature beats can occur in any organic heart disease, its most common cause is coronary artery disease. With
