title: Development of a serial comparison program for conduction defects, acute myocardial infarction, and the use of additional leads.
abstract: Serial comparison of electrocardiograms (ECGs) is a useful tool in clinical diagnostic ECG and an enhancement to computer ECG analysis. When an analysis algorithm is modified, the corresponding serial comparison program needs to be updated accordingly. The new Philips diagnostic algorithm increased the number of leads in the ECG from the traditional 12 leads to 16, making it possible to diagnose right ventricular infarct/injury based on right-sided lead V4R. To keep pace with the widespread reperfusion therapy for acute myocardial infarct, the serial comparison program was revised to recognize the rapid ECG changes in patients with ST-elevation myocardial infarct following successful reperfusion therapies. The serial comparison program was also enhanced to split "combined" statements in the category of ventricular conduction delay (includes incomplete ventricular conduction delay and bundle-branch blocks) and compare each of the statements separately.
