1. A method of detecting retrograde conduction from a ventricular stimulation site to avoid pacemaker-mediated tachycardia during substantially concurrent, multi-site ventricular stimulation, the method comprising:

  • determining that a high ventricular stimulation rate is sustained for a predetermined number of cycles during an atrial sensing mode;

    identifying two or more ventricular stimulation sites associated with a retrograde conduction pathway;

    temporarily interrupting substantially concurrent stimulations to the two or more ventricular stimulation sites; and

    alternating stimulation to the two or more ventricular stimulation sites.
