Implantable heart stimulator and method for trending analysis of ventricular activation time

摘要

The invention refers to a method and an apparatus for assessing ventricular activation time by determining a point in time t1 of an initial positive deflection on a far-field electrogram and a point in time t2 of a first peak of the negative deflection on a near-field electrogram of a same heart cycle and determining a time difference between points in time t1 and t2 said time difference representing the ventricular activation time.
