The analysis of linear/nonlinear coupling between heart rate and QT intervals
Original language description
Two groups of subjects (21 healthy, 21 hypertensive patients) were tested during two measurement protocols (exercise, tilt). Two models of QT-RR coupling were tested - linear (LM) and nonlinear (NLM). QTc reproducibility was used as evidence of model validity. Results: LM was significantly better (lower QTc irreproducibility) than NLM (P<;0.01) during the tilt-table test. The differences were not significant during the exercise test; NLM was slightly better in hypertensive patients, LM in healthy subjects. Maximal irreproducibility of QTc over subjects was found in both tests with NLM. Conclusion: Evidence of QT-RR nonlinearity cannot be based on minimal error between QT and model QT. QTc reproducibility must also be tested and the excitation specificity of QT-RR coupling must be considered.Two groups of subjects (21 healthy, 21 hypertensive patients) were tested during two measurement protocols (exercise, tilt).
