Abstract
A three-dimensional electrocardiogram display method for 3-D representation of a plurality of cardiac signals is provided. In this method, a 3-D rectangular coordinate system is defined to display the 3-D representation of the cardiac signals. Further, an amplitude display scheme, preferably an amplitude-to-color mapping table, is defined to assign various quantization levels of amplitude to specified distinctive colors. By graphic processing and display means, the 3-D representation of the cardiac signals can be generated and displayed. The physicians can choose to observe the 3-D graph in various views, including perspective view, sectional view, and top rectangular view. This allows the physicians to make diagnosis of heart diseases by observing just one or two 3-D representations of the cardiac signals. The physicians can thus have an overall integral view over a plentiful number of cardiac signals and thereby make diagnosis about the heart conditions of the patient more easily.
