Systems and methods are provided for automated assessment of regional myocardial function using wall motion analysis methods that analyze various features / parameters of patient information (image data and non-image data) obtained from medical records of a patient. For example, a method for providing automatic diagnostic support for cardiac imaging generally comprises obtaining image data of a heart of a patient, obtaining features from the image data of the heart, which are related to motion of the myocardium of the heart, and automatically assessing regional myocardial function of one or more regions of a myocardial wall using the obtained features.

The present invention provides a method and apparatus for assessing ventricular function on a chronic basis using a plurality of electrodes disposed on or about a left ventricle and / or a right ventricle—and optionally, at least one mechanical or metabolic sensor—all operatively electrically coupled to an implantable medical device. The plurality of electrodes are preferably spaced-apart so that at least one electrode is disposed electrical communication with a discrete volume of ventricular tissue. In one embodiment, the discrete volume of tissue is defined by multiple longitudinal and axial planes as known and used in the medical arts. Thus, according to the present invention, at least one electrode couples to appropriate sensing circuitry and essentially provides a localized electrogram (EGM) that, when compared to other EGMs, provides for configurable, localized delivery of therapeutic pacing stimulus, diverse impedance-sensing vectors, various diagnostic information regarding myocardial function and / or anti-tachycardia pacing.

CAD (computer-aided diagnosis) systems and applications for cardiac imaging are provided, which implement methods to automatically extract and analyze features from a collection of patient information (including image data and / or non-image data) of a subject patient, to provide decision support for various aspects of physician workflow including, for example, automated assessment of regional myocardial function through wall motion analysis, automated diagnosis of heart diseases and conditions such as cardiomyopathy, coronary artery disease and other heart-related medical conditions, and other automated decision support functions. The CAD systems implement machine-learning techniques that use a set of training data obtained (learned) from a database of labeled patient cases in one or more relevant clinical domains and / or expert interpretations of such data to enable the CAD systems to “learn” to analyze patient data and make proper diagnostic assessments and decisions for assisting physician workflow.

The invention relates to a method and a post-operative care unit for analysing and quantifying an ultrasound tissue Doppler imaging (TDI) signal from a transducer fastened on the myocardium to obtain a parameter indicating regional cardiac ischaemia or correlates with global hypokinetic heart function. This has the advantage over manually operated probes that it can be automated and used continuously over long time. According to the method, a TDI signal trace corresponding to at least one of tissue velocity, strain or strain rate is extracted and correlated with an electrocardiogram to define subsections within a cardiac cycle in the extracted trace corresponding to the early systolic phase and the post-systolic phase. Then, a velocity, strain or strain rate is read in at least the post-systolic phase of the extracted trace, and a parameter which is a function of one of these readings and which indicates ischaemia or global hypokinetic function is generated.
