She underwent a modified Blalock-Tausig shunt at the age of 2 months to treat increasing cyanosis. She did well and is waiting to complete single ventricle palliation.

The patterns of P mitrale and P pulmonale are generally well recognized. Morris and co-workers' reported that differences in the contour of the terminal portion of the P wave in precordial lead V, separated subjects with essentially normal hemodynam-ic finding...
متن کاملIdentification of Subsonic P-Waves
A field trial was conducted to test the existence of subsonic (Vp < 331 m/s) P-waves previously reported in the literature. A 1-m-long reverse profile was acquired with three-component (3C) geophones on a sandy silt (unified classification ML). The silt had a porosity of 54%, a degree of water saturation of 63%, and a plasticity index of 10. No subsonic P-waves were observed, although highfrequ...
