The construction method of the QRS loop in myocardial infarction.


In order to investigate the relation between the infarcted area in myocardial infarction and the change of the QRS loop, the following method was tried. The normal QRS loops in 3 planes were constructed with the digital computer. Then the vector of an optional segment corresponding to infarction was diminished and the QRS loops were constructed. The comparison of the QRS loops in clinical cases and in the construction method was made and the vectorcardiographic findings to estimate the infarcted area were discussed.
