Right @entity1188 due to @entity741 can be diagnosed by a right precordial electrogram or by first-pass radionuclide angiography (FPRNA). Prior FPRNA studies have shown that @entity299 after blunt @entity764 ( @entity296 ) is most often due to right @entity67 . We hypothesized that right @entity67 due to @entity741 and @entity296 should produce similar ECG changes due to myocyte disruption. The purpose of our study was to evaluate the diagnostic value of the right precordial electrogram in suspected @entity299 . Thirty-five @entity1 with suspected @entity296 based on mechanism of injury/clinical findings and no history of clinical @entity299 were enrolled prospectively. All @entity1 had conventional ECG, right precordial electrogram, and FPRNA studies. Twenty @entity1 had normal cardiac scans (group 1); percentage of myocardial @entity908 kinase (CK-MB) was measured in 12 of these @entity1 and was less than 5% in 11. Fifteen @entity1 had abnormal cardiac scans (wall motion abnormality and/or decreased right ventricular ejection fraction) (mean, 34% +/- 7% [SD]; normal, greater than 40%) (group 2); percentage of CK-MB was measured in 13 of 15 @entity1 and was less than 5% in all 13. Conventional ECGs and right precordial electrograms in all @entity1 were analyzed for differences in heart rate, PR interval, QRS duration, @entity1162 complex and ST segment. There were no significant differences between group 1 and group 2 @entity1 . No @entity1 with @entity296 diagnosed by FPRNA had elevated ST segments in V4R through V6R or a percentage CK-MB of more than 5%.(ABSTRACT TRUNCATED AT 250 WORDS)
