摘要:
Methods and systems are presented for using an ICD to detect myocardial ischemia. One such method includes sensing via an implantable cardiac-rhythm-management device (ICRMD) a signal indicative of cardiac pressure determining via a processor associated with the ICRMD, a derivative signal that is a first derivative of the sensed signal measuring via the processor, a maximum positive value of the derivative signal measuring via the processor, a maximum negative value of the derivative signal and indicating via the processor, an ischemia based on a comparison of a ratio of the maximum positive value to the maximum negative value with a predetermined value.
