Cardiac arrhythmias in the elderly: clinical aspects.

Abnormal cardiac rhythms appear more normal frequently in the elderly population. Studies confirm that the incidence of serious or life-threatening arrhythmias, including Mobitz type II atrioventricular block and ventricular tachycardia, increases the incidence of cardiac disease in this population group. As age progresses, the hemodynamic manifestations are more symptomatic and require specific therapy, including cardiac pacemakers and antiarrhythmic agents.
