Excitation Specificity of Repolarization Parameters
Original language description
QT/RR coupling was analyzed in two groups of subjects (healthy and hypertensive) with two protocols (exercise and tilt). A dynamic model of QT/RR coupling with 3 optimized parameters was used to analyze dynamic properties (memory and restitution) and toeliminate QT hysteresis. Linear and nonlinear models were used to analyze static properties. Parameter reproducibility was tested by a bootstrap methodology. The linear model is better with the tilt test, the nonlinear model is better in hypertensive patients with the exercise test. QT memory differs significantly between the exercise and tilt test in both groups. The QT/RR slope is steeper in the exercise test and QT adaptation faster with the tilt test. The excitation specificity of QT parameters mayexplain genetic dependent triggers of arrhythmias and QT/RR nonlinearity.
