[The value of continued dynamic electrocardiography in the sick sinus syndrome]

An assessment was made of the usefulness of continuous dynamic ECG (CDE) in diagnosis of the sick sinus syndrome (SSS). It was found that CDE has the following advantages: ready repeatability; control of patients during such physiological activities as sleep; recording of the possibly fleeting and intermittent pathological episodes that characterise SSS. The conclusion is drawn that CDE is the soundest technique for the investigation of SSS, whereas electrophysiological examination, albeit complementary, could be limited to cases whose interpretation proves more difficult.
