Patent ID: 8634902

Claim:
A cardiac analysis system comprising: an implantable medical device (IMD) including electrodes configured to be positioned proximate to a heart, the electrodes sensing cardiac signals of the heart including first cardiac signals associated with a clinical ventricular tachycardia (VT) event of the heart and second cardiac signals associated with an induced VT event of the heart; at least one sensor configured to measure non-electrical cardiac parameters of the heart including first non-electrical cardiac parameters associated with the clinical VT event and second non-electrical cardiac parameters associated with the induced VT event and wherein the at least one sensor is selected from the group consisting of a blood pressure sensor, a blood oxygen sensor, a photoplethysmograph (PPG) sensor, a glucose sensor, an acoustic sensor, and a saturated venous oxygen sensor; and an external device configured to receive the first and second cardiac signals, the external device configured to receive the first and second non-electrical cardiac parameters, the external device configured to present the first cardiac signals and the first non-electrical cardiac parameters with the second cardiac signals and the second non-electrical cardiac parameters to enable determination of when the clinical VT event and the induced VT event are a common type of VT event.
