Syncope in the elderly. Report of 3 cases with sick sinus syndrome.

Three cases of arrhythmia-induced syncope in the elderly are reported. The patients all showed some features of the sick sinus syndrome and had aortic ejection murmurs. Ventricular tachycardia occurred in 2 patients. The importance of trying to record an arrhythmia during a syncopal attack is stressed, as are the adverse effects of many drugs commonly prescribed in this age group. The relationship between the arrhythmias found and their association with aortic stenosis are discussed.
