随着人们对心肌梗塞的认识及治疗的深入,人们发现心肌梗塞坏死心肌的广度是确定左室功能失调及室性心律失常的最重要的指标。这些发现启发人们努力去创立确定心肌梗塞体积的敏感而无损伤的方法。目前我们已发现了多种确定心肌梗塞体积的方法,包括CPK酶学法、核素显像法、磁共振法、左室造影法、CT法,扇超扫描法、胸前导联QRS标测法[1]后四种方法均为间接推断,准确性较差。核素显像法 As people’s understanding of myocardial infarction and treatment depth, people found that the extent of myocardial infarction myocardial necrosis is to determine the most important indicators of left ventricular dysfunction and ventricular arrhythmias. These findings inspired people to work hard to create a sensitive, non-invasive way of determining the volume of myocardial infarction. We have now identified a number of methods to determine the volume of myocardial infarction, including CPK enzymatic, radionuclide imaging, magnetic resonance imaging, left ventricular angiography, CT, fan scans, and precordial QRS mapping After the method [1] four methods are indirect inference, the accuracy is poor.
