Continuous Recording of Direct Arterial Pressure and Electrocardiogram in Unrestricted Man
Key Points
- The aim is to develop a system for recording direct arterial pressure and ECG without restricting activity.
- Developed a magnetic tape recording system for arterial pressure and ECG
- Allows for analysis at various speeds and produces 24-hour records on paper
- Includes a marker for timing relevant events.
- The system is indicated to be safe and reliable based on initial experiences.
Abstract
A system has been devised which records direct arterial pressure, electrocardiogram, and other variables in man with no restriction of activity. The advantage of this system is that the record is on magnetic tape, and it is possible to replay the records at various speeds to analyse each beat or to produce an entire 24-hour record on a few feet of paper. A marker allows the timing of relevant events. Initial experience with this procedure indicates that is is safe and reliable.
