title: Controlled study of 24-hour ambulatory electrocardiographic monitoring in patients with transient neurological symptoms.
abstract: Sixty unselected patients with transient neurological symptoms underwent 24-hour ambulatory electrocardiographic (ECG) monitoring. Haemodynamically significant arrhythmias were observed in 32% of patients, but in only 3% of an age-  and sex-matched control group. Nine patients received specific anti-arrhythmic therapy, which resulted in marked symptomatic improvement in each case. It is argued that 24-hour ECG monitoring is a valuable diagnostic tool in the investigation of transient neurological symptoms.
