Abstract

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.

Claims

1. An apparatus for determining the location of a MI/I event in a subject, comprising an implantable device including a plurality of sensors adapted to be positioned in and around the heart, the device further including means for analyzing the changes in electrogram signals received from the sensors and means for determining the location using dipole projection, wherein a plurality of the sensors are positioned within the heart.
