Abstract :
To obtain a more complete picture of cardiac electrical activity, data is acquired from an array of electrodes on the torso surface during a clinical procedure in which a balloon is inflated in an artery to clear obstructions. The goal is to analyze the data and extract features which reveal the occurrence and location of the balloon inflation, and to relate these features to underlying physiological changes. A multidimensional time and space wavelet transform is applied to the data to enable extraction of relevant features. Both scaling and wavelet coefficients contain useful information
