1. A method, comprising:

  • sensing atrial and ventricular events representative of cardiac rhythms;

    detecting at least one of a ventricular tachycardia and a ventricular fibrillation;

    analyzing the cardiac rhythms during a first time interval for assessing an origin of the at least one of a ventricular tachycardia and a ventricular fibrillation, the first time interval started when the at least one of a ventricular tachycardia and a ventricular fibrillation is detected; and

    delaying or inhibiting a ventricular tachycardia therapy if the origin of the at least one of a ventricular tachycardia and a ventricular fibrillation is in an atrium.
