May enable simpler ECG monitoring devices; leaves open prospective validation in diverse cohorts.
A simple microprocessor algorithm using gradient and duration criteria can reliably detect ECG R-waves with an error rate of approximately 1%.
Coleman et al. (1979) studied ECG monitoring in coronary care units. Microprocessor algorithm for R-wave detection vs. Self-adjusting systems was evaluated on Total errors due to false positives and negatives. A simple microprocessor algorithm for ECG R-wave detection achieved a total error rate of approximately 1% for false positives and negatives when assessed on patient tapes.
