Development of a QRS detector algorithm for ECG's measured during centrifuge training

This paper describes a QRS detector algorithm for ECG's measured during centrifuge training of fighter pilots at the Netherlands Aerospace Medical Centre (NAMC). Due to the low quality of the ECG signal during centrifuge training a very robust QRS detector is necessary. An algorithm has been developed which uses lower and upper thresholds in spatial velocities to decide if a detected peak is a R-top. The performance (S=99.41% and PP-99.77%) of this new QRS detector was substantially higher than a frequently used QRS detector in the literature.
