3D reconstruction of myocardial ischaemia from 16 site praecardial 24-hour ST mapping

Summary form only given. The use of a three-dimensional CAD program. Autocad 10, to display the ST data in a 3D format is described. Each channel of ST data is converted to a polyline. The polylines representing ST change over time are structured as a grid to reproduce the physical positioning of the electrodes on the chest. In each of the four planes generated by the polylines of the grid, a mesh is layered over the polylines to correlate the ST change in each plane. A simultaneous mesh is generated of the change in heart rate. Such a modeling technique alloys a unique perspective of ischemic episodes in the 24 hours after anesthesia. Myocardial events can be correlated to other myocardial indices such as heart rate, systolic, diastolic and mean blood pressure, and pulmonary artery measurements if available. A 16-channel praecardial map may provide the potential for defining the area of ischaemia, and from this, the site of the comprised coronary arterial tree
