1. An implantable medical device comprising:

  • a tachyarrhythmia detector that detects a ventricular tachyarrhythmia in a heart of a subject based on an electrocardiogram signal measured for said heart;

    an impedance determining unit that determines a cardiogenic impedance signal representative of volumetric dynamics of at least one ventricle of said heart; and

    a tachyarrhythmia classifier that classifies said ventricular tachyarrhythmia as a stable ventricular tachyarrhythmia or an unstable ventricular tachyarrhythmia based on said cardiogenic impedance signal.
