TREATMENT OF VENTRICULAR ARRHYTHMIAS IN OLDER ADULTS

OBJECTIVE: To review the prognosis and management of ventricular arrhy thmias (VA) in persons with and without heart disease with emphasis on older adults. DATA SOURCES: A computer-assisted search of the English language literature (MEDLINE database) followed by a manual search of the bibliographies of pertinent articles. STUDY SELECTION: Studies on the prognosis and management of VA in persons with and without heart disease were screened for review. Studies in older people and recent s tudies were emphasized. DATA EXTRACTION: Pertinent data were extracted from the reviewed articles. Emphasis was on studies involving the old er persons. Relevant articles were reviewed in depth. DATA SYNTHESIS: Available data about the prognosis and management of VA in persons wit h and without heart disease, with emphasis on studies involving older people, were summarized. CONCLUSIONS: VA in older persons without hear t disease should not be treated with antiarrhythmic drugs. Class I ant iarrhythmic drugs should not be used to treat VA in older persons with heart disease. Beta blockers should be used to treat complex VA in ol der persons with ischemic or nonischemic heart disease if there are no contraindications to beta blocker therapy. The use of amiodarone in t reating complex VA should be reserved for life-threatening ventricular tachyarrhythmias in older persons who cannot tolerate or who do not r espond to beta blockers. VA associated with congestive heart failure s hould be treated with angiotensin converting enzyme inhibitors. If old er patients have life-threatening recurrent ventricular tachycardia or ventricular fibrillation resistant to antiarrhythmic drugs, invasive intervention should be performed. The automatic implantable cardiovert er-defibrillator is recommended in older patients who have medically r efractory sustained ventricular tachycardia or ventricular fibrillatio n.
