Ventricular ectopic activity: prevalence and risk.

The American Journal of Cardiology
F C Messineo

Abstract

Ambulatory electrocardiographic monitoring and the frequent use of stress electrocardiography have been important tools in characterizing the prevalence and prognostic importance of ventricular ectopic activity in both healthy persons and patients with organic heart disease. These studies have demonstrated that ventricular ectopy is not uncommon in persons with no evidence of heart disease. However, it is rarely of high density or repetitive, and even when frequent or repetitive, or both, carries little, if any, risk of sudden death in patients without syncope. However, in patients with organic heart disease and in certain clinical settings, frequent and repetitive ventricular ectopy identifies a population at high risk for arrhythmia-induced syncope or sudden death. These rhythm disturbances have particular prognostic importance in ischemic heart disease with depressed left ventricular function and hypertrophic cardiomyopathy. Patients with presyncope or syncope and structural heart disease who demonstrate frequent and repetitive ventricular ectopy are also a high-risk group. Therefore, individual risk stratification is important in deciding whether and how to treat patients with ventricular ectopy.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Cardiovascular Diseases: Risk Factors

Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
