Ventricular conduction stability test: a method to identify and quantify changes in whole heart activation patterns during physiological stress

Abstract Aims Abnormal rate adaptation of the action potential is proarrhythmic but is difficult to measure with current electro-anatomical mapping techniques. We developed a method to rapidly quantify spatial discordance in whole heart activation in response to rate cycle length changes. We test th...
