Ambulatory monitoring of arterial blood pressure. Comparison between blood pressure measurements obtained with the Remler M 2000 portable recorder and by radiotelemetry under laboratory conditions and during everyday activities.

Simultaneous indirect and direct arterial blood pressure measurements were performed with a Remler M 2000 (RM) portable recorder and by radiotelemetry (RT) in 21 subjects under various conditions such as rest in the supine position and in an 80 degree upright position on a tilting table, during bicycle ergometry, physical exercise on the terrain and under the emotional stress of driving a car. There is a good correlation between semiautomatic pressure measurements carried out with the RM portable recorder and radiotelemetric data. The differences observed are basically due to the auscultation method. But the RM has an advantage over the auscultation method in that it objectively registers the Korotkov sounds and records them on a tape, not only under laboratory conditions but also during everyday activities.
