Ambulatory electrocardiography in the elderly: an audit

In a retrospective analysis of 264 episodes of ambulatory electrocardiography (AECG) in 252 elderly out-patients the overall diagnostic yield was only 12 per cent. However, AECG was found to be of significant value in detecting symptomatic tachyarrhythmias, and in confirming the diagnosis of the 'sick sinus syndrome'. The AECG results influenced the management plan in at least 16 per cent, and changes in drug treatment in 10 per cent. When interpreted critically, AECG is useful tool in the investigation of elderly patients with symptoms such as syncope, faintness, dizziness and unexplained falls.
