초록 ▼

The present disclosure provides an apparatus and method of detecting ischemia with a pressure sensor. The method can include obtaining a pressure signal and determining a pressure rate of change. The method can also include identifying at least one of impaired relaxation and impaired contractility i

대표청구항 ▼

1. An implantable medical device comprising: an implantable pressure sensor providing a signal indicative of a patient's blood pressure;a data processing module coupled to the pressure sensor, the data processing module configured to determine a blood pressure rate of change based on the blood pressure signal;the data processing module configured to identify at least one of impaired relaxation and impaired contractility based on a maximum value of the blood pressure rate of change and to detect ischemia in response thereto; anda therapy module comprising a pacing electrode coupled to the data processing module and configured to deliver therapy to the patient responsive to the identification of one of impaired relaxation and impaired contractility. 2. The device of claim 1 wherein the maximum value comprises maximum rate of pressure increase. 3. The device of claim 1 further comprising an implantable transmitter coupled to the processing module and providing a transmission responsive to the identification of one of impaired relaxation and impaired contractility. 4. The device of claim 1 wherein the data processing module is further configured to activate the pressure sensor to obtain the indicative signal therefrom over a defined sample period. 5. A method of delivering a therapy to a patient, comprising: employing a pressure sensor implanted in the patient to provide a signal indicative of a patient's blood pressure;employing a processing module implanted in the patient and coupled to the pressure sensor to determine a maximum value of blood pressure rate of change from the blood pressure signal;employing the implanted processing module to identify at least one of impaired relaxation and impaired contractility based on the maximum value of the blood pressure rate of change and to detect ischemia in response thereto; andemploying a therapy module comprising a pacing electrode implanted in the patient and coupled to the processing module to deliver therapy to the patient responsive to the identification of one of impaired relaxation and impaired contractility. 6. The method of claim 5 wherein the pressure sensor is located in one of the left ventricle, the right ventricle, the left atrium, and the pulmonary artery. 7. The method of claim 6, further comprising obtaining a complementary signal comprising at least one of the patient's: heart rate, heart rate variability, time of day, heart sounds, patient activity, impedance, core body temperature, respiration rate, mixed venous oxygen saturation, wall contractility, wall tension, pulse oximetry, pulse pressure, number of premature ventricular contractions, non-sustained ventricular tachycardia, and sustained ventricular tachycardia. 8. The method of claim 7 wherein the processing module analyzes the blood pressure signal and the complementary signal to determine if the pressure signal represents a normal hemodynamic response. 9. The method of claim 5 wherein the maximum value comprises maximum rate of pressure increase.
