RELIABLE R-WAVE DETECTION FROM AMBULATORY SUBJECTS.

Research output: Contribution to journalArticle

Abstract

The electrode-to-skin interface as a source of artifacts has been investigated. The test device applies a force of 5 newtons to simulate the generation of movement artifacts. Four-day-long tests at 14 thoracic locations identified four optimal locations for electrodes. Artifacts generated by an exercise protocol have been used to evaluate the long-term performance of electrodes. The author describes the design of an ECG amplifier and a QRS detection circuit that has a power consumption of only 150 microwatts and operates on a single 5-volt supply. The performance of the hardware was tested with 15 minutes of a standardized set of recorded arrhythmias and 15 minutes of noise signals encountered under ambulatory conditions.
