1. A method of cardiac signal analysis comprising:

  • sensing a first cardiac event;

    configuring template parameters for analysis of the first cardiac event;

    defining a first sensed signal for the first cardiac event using the template parameters;

    sensing a second cardiac event;

    defining a second sensed signal for the second cardiac event using the template parameters;

    comparing the second sensed signal to the first sensed signal to determine whether the first sensed signal and template parameters are suitable for defining a cardiac event template; and

    if the first sensed signal and template parameters are suitable, retaining the first sensed signal and template parameters for using to define a cardiac event template;

    or, if the first sensed signal and template parameters are not suitable, discarding the first sensed signal and template parameters from use in defining a cardiac event template.
