1. A method comprising:

  • providing cardiac pacing with an implanted pacemaker;

    using the pacemaker to measure an atrial ventricular conduction delay (AV delay) for each of a plurality of cardiac cycles;

    storing the measured AV delays in the pacemaker;

    transmitting the stored AV delays to an external device as AV delay data;

    using the AV delay data to evaluate a medical status; and

    correlating the measured AV delays with a trigger condition to determine whether to initiate collection of data related to patient-indicated symptoms.
