Abstract
An implantable medical device that continuously measures the patient's intracardiac ventricular impedance. Extracts cardiac performance information based on the intracardiac impedance, including amplitude, timing and variability of cardiac contraction function. The device records and analysis trends in the performance information. The device identifies changes, which exceed the selected threshold limits. In the event of an incipient crisis, the device transmits an alert message.
