to further assess these characteristics we evaluated the effect of abrupt short-to-long change in ventricular cl on the phenomenon of macroreentry within the hps ( re-hps ) in 20 patients in whom re-hps occurred during application of a ventricular extrastimulus ( v2 ) at a constant ventricular cl ( method i ) and/or with abrupt short-to-long change in cl ( method ii ) .
