我们设计了一个新的计算算法，借助后续的导联7，8，9导联信号V7，V8,V9，以改善心电检测中孤立和心肌梗死信号的检测。-We designed a new computer algorithm to improve ECG detection of isolated and

combined posterior myocardial infarct using extended posterior leads V7, V8 and V9. ECG criteria for PMI include “age” (acute, recent, age indeterminate or old) and probability” (consider, probable or definite) infarct.
