Abstract
Official abstract text for this publication.
Implantable systems, and methods for use therewith, are provided for monitoring for an impending myocardial infarction. A signal indicative of changes in arterial blood volume is obtained. Such a signal can be a photoplethysmography signal or an impedance plethysmography signal. For each of a plurality of periods of time, a metric indicative of the areas under the curve of the signal or number of inflections in the signal is determined. An impending myocardial infarction is monitored for based on changes in the metric indicative of the area under the curve of the signal or number of inflections in the signal, and an alert and/or therapy is triggered in response to an impending myocardial infarction being predicted.
First claim
Opening claim text (preview).
What is claimed is: 1. For use with a chronically implanted device, a method for monitoring for an impending myocardial infarction (MI), comprising: (a) obtaining a first signal indicative of changes arterial volume, the first signal comprising one of a photoplethysmography (PPG) signal or an impedance-plethysmography (IPG) signal, and a second signal indicative of electrical cardiac activity, the second signal comprising one of an electrocardiogram (ECG) signal or an intracard…
