an electrocardiogram showed lateral st-segment depressions and t-wave inversions. creatine kinase measurements were normal but his troponin t was elevated at 0.39 ng/ml. coronary angiography showed diffuse 3-vessel disease and he was admitted for coronary artery bypass graft (cabg) surgery. mr c ...
We perform Q Lg tomography for the northeastern part of North America. Vertical broadband seismograms of 473 crustal earthquakes recorded by 302 stations are processed to extract the Lg amplitude spectra. Tomographic inversions are independently conducte
These two main magmatic environments coincide with a region of low P-wave velocity anomalies23. The shallow (0–9 km) and intermediate depth (10–19 km) portions are dominated by a huge plexus of P-wave high-velocity body located in the central-southern sector of the volcano and ...
Inversions of the S-wave velocity structures in Songpan-Ganzi block, Qiang-Tang block, Lhasa block and the faulted rift zone were obtained from the dispersion data. The results show that significant lateral variation of the S-wave velocity structures among the different blocks exists. The path ...
In 8 of these 22 patients, the infarct was silent in the sense that no ST segment elevation or Q waves were seen, although ST depressions or T wave inversions, or both, in all but one patient were compatible with subendocardial infarction. The results indicate that the standard ...
