A newly devised system using a modified Holter recorder and Millar tip transducer provided reliable, simple, and safe continuous recording of direct arterial pressure and ECG in ambulant patients.
A system providing high quality direct arterial blood pressure recordings and electrocardiograms in ambulatory patients was devised using a modified commercially available Holter type magnetic tape recorder together with a microminiature Millar (3F) tip transducer. This system did not require a perfusion line and solved the major drawbacks of other available systems. Pressure and electrocardiographic data were fed directly from the playback unit into a minicomputer for automatic beat to beat waveform analysis. Thus the blood pressure and RR interval variability signals could be simultaneously analysed with autoregressive modelling techniques to provide a quantitative estimate of sympathovagal balance in ambulant patients. The system was reliable, simple, and safe to use.
Pagani et al. (Thu,) conducted a other in Ambulatory patients. Continuous recording system using modified Holter recorder and Millar (3F) tip transducer was evaluated on System reliability, simplicity, and safety. A newly devised system using a modified Holter recorder and Millar tip transducer provided reliable, simple, and safe continuous recording of direct arterial pressure and ECG in ambulant patients.
