[Evaluation of late potentials in patients with acute myocardial infarction--relationship with right ventricular infarction].
Late Potential (LP) is known to be easily detected in inferior myocardial infarction (AMI) patients. And it is also well known that high incidence of LP positive in the patients with arrhythmogenic right ventricular dysplasia are seen. However, there is no report that LP in patients with right ventricular (RV) infarction is easily detectable. This following study was conducted to distinguish how LP was affected by RV infarction. 36 inferior AMI patients (27 male, 9 female) who were performed PTCA in acute stage were selected. They were divided into three groups in accordance to the position of infarct related artery (Group A is proxysmal RCA, Group B is distal RCA and Group C is LCx). There were no significant difference among these groups in terms of filtered QRS duration and last 40 msec RMS voltage. It was concluded that RV infarction could not affect to the rate of LP positive in inferior AMI patients.
