Estimating infarct severity from the ECG using a realistic heart model

The early phase of myocardial infarction is accompanied by changes in the ST segment of the ECG. This makes the ST segment the clinical marker for the detection of acute myocardial infarction. The determination of the infarct severity, location and size of the myocardial tissue at risk will support clinical decision making. In this study we used an inverse procedure to estimate the location and size of the infarcted heart region. The method estimates the local transmembrane amplitude based on the ECG amplitude near the J-point of the standard 12 leads signals using a patient specific volume conductor model. For the 5 available patient cases the positions as well as the size of the estimated infarct region were in accordance with results based on MRI

Validation of infarct size and location from the ECG by inverse body surface mapping

This paper describes the incorporation of body surface mapping algorithms to detect the position and size of acute myocardial infarctions using standard 12 lead ECG recording. The results are compared with the results from cardiac MRI scan analysis. In case patient specific volume conductor models are used, the position of the infarction could be accurately determined. When generalized patient volume conductor models were examined, the estimation of the infarct position became significantly less accurate. The calculations of the size of the infarctions need further improvement

The Cardiology Information System: the need for data standards for integration of systems for patient care, registries and guidelines for clinical practice

The building blocks come together, finally! Already three decades ago we were dreaming of the complete Cardiology Information System. However, at that time the computer programmers explained that it was too early. In the subsequent year information tech- nology (IT) specialists, replacing the programmers, gave similar messages. Business interests of medical equipment industries seemed not to support data exchange; however this has changed in recent years. Now, finally the pieces come together. The bricks have been laid, the blocks have been made, and the system can be built
