IMPLANTABLE MYOCARDIAL ISCHEMIA DETECTION, INDICATION AND ACTION TECHNOLOGY

摘要

One embodiment enables detection of MI/I and emerging infarction in an implantable system. A plurality of devices may be used to gather and interpret data from within the heart, from the heart surface, and/or from the thoracic cavity. The apparatus may further alert the patient and/or communicate the condition to an external device or medical caregiver. Additionally, the implanted apparatus may initiate therapy of MI/I and emerging infarction.

主权项

1. A method of monitoring a heart for evidence of myocardial ischemia/infarction (MI/I), comprising:
monitoring the heart using a pacemaker device implanted into a subject, the pacemaker device including a pacing electrode and a plurality of electrical sensors adapted to sense an electrogram signal, the electrical sensors being positioned at locations including the heart and vascular system, wherein only one of the electrical sensors adapted to sense an electrogram signal is positioned in the heart; and determining whether evidence of MI/I is present in the subject, using the electrogram signal; wherein at least some of the electrical sensors used in determining whether evidence of MI/I is present in the subject are also used to sense a need to pace the heart.
