Abstract
The invention concerns a method of signaling an internal status of an implantable cardiac stimulation device, which status is defined by a value of a status parameter, including the steps: a) Recording a measurement value (S ) representing the status parameter, b) Ascertaining the existence of the status by comparison of the measurement value with a comparative value (S ), c) Delivering a signal pulse with a predetermined, measurable pulse parameter, wherein the pulse parameter is uniquely associated with the status if the measurement value corresponds to the comparative value within predetermined limits (S ). In accordance with the invention the time difference of equal, predetermined phases of two successive, periodically recurring events prior to delivery of the signal pulse is measured (S ), and then the signal pulse is delivered prior to or after the next expiry of the measured time difference by a predeterminable period of time uniquely associated with the status (S S S ). The invention further concerns a cardiac stimulation device for carrying out that method.
