Factors affecting the sensitivity of computerized ECG analysis inidentifying previous myocardial infarction

摘要

We investigated to what extent the ECG sensitivity in identifyingprevious myocardial infarctions (MI) is affected by theclinical/epidemiological criteria having been used in the acute MIstage. The sensitivity was determined analyzing the 12 lead resting ECGsduring a follow-up of 432 long-term survivors who suffered three to 13years ago from MI. The ECG analysis in the follow-up was performed usingthe Hannover ECG program. The sensitivity values determined ranged from61.3% up to 88.4% depending on the criteria used for caseselection
