Time Course of ECG Depolarization and Repolarization Changes during Ischemia in PTCA Recordings

OBJECTIVES: In this work we studied the temporal evolution of changes in the electrocardiogram (ECG) as a consequence of the induced ischemia during prolonged coronary angioplasty, comparing the time course of indexes reflecting depolarization and those reflecting repolarization. METHODS: We considered both local (measured at specific points of the ECG) and global (obtained from the Karhunen-Love transform) indexes...
