1. A method of obtaining information related to a cardiac cycle comprising:
- receiving a physiological data signal from a mechanical characteristic sensor, where the physiological data signal is indicative of a mechanical cardiac function;
deriving cardiac event markers from attributes of the physiological data signal; and
generating a cardiac event marker signal using the cardiac event markers, the cardiac event marker signal identifying cardiac cycle timing characteristics.

Abstract
The implantable medical device (IMD) system disclosed here utilizes one or more cardiac sensors that measure mechanical characteristics of the heart, such as left ventricular acceleration or right ventricular pressure. The raw sensor data is collected and processed by the IMD, which derives one or more mechanical event marker signals from features, traits, and characteristics of the sensor data waveforms. The mechanical event marker signals are wirelessly transmitted to an external monitor device for display.
