Abstract
This work investigates the relationship between the QT interval and its preceding TQ interval of the electrocardiogram (ECG) recorded under the handgrip isometric exercise. The experimental results at the ECG scale in this work show that the relationship between these intervals is similar to the well established restitution curve observed in isolated cells, between the action potential duration and its preceding diastolic interval. This result opens new perspectives for the analysis of ECG signals.
