Abstract :
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
