BACKGROUND Early repolarization, indicated on the standard 12-lead ECG, has recently been associated with idiopathic ventricular fibrillation in patients without structural heart disease. It is unknown whether there is an association between early repolarization and ventricular arrhythmias in the coronary artery disease (CAD) population. METHODS AND RESULTS Patients with CAD with implantable ...
BACKGROUND Cuff tear arthropathy is the primary indication for total reverse shoulder arthroplasty. In patients with pseudoparalytic shoulders secondary to irreparable rotator cuff tear, reverse shoulder arthroplasty allows restoration of active anterior elevation and painless shoulder. High rates of glenoid notching have also been reported. We designed a new reverse shoulder arthroplasty with ...
BACKGROUND Alar rim deformities such as retraction, notching, collapse, and asymmetry are common problems in rhinoplasty patients. Although alar rim deformities may be improved through rhinoplasty, this area is prone to late changes because of scarring of the soft triangles and a paucity of native structural support. The purpose of this study was to analyze the effect of alar contour grafts on ...
OBJECTIVE To evaluate the functional results from reverse arthroplasty and its complications and relationships with types of injury. METHODS Twenty-seven shoulders (26 women and one man) were treated. The patients were assessed using the UCLA functional scale. The implant used was the Delta Xtend Depuy(®) model. The injuries were classified using the Seebauer method for the degree of arthropl...
Position of hip resurfacing component affects strain and resistance to fracture in the femoral neck.
BACKGROUND Retrieval studies have suggested that the cause of femoral implant failure after metal-on-metal hip resurfacing is multifactorial. Both varus positioning of the femoral component and notching of the superior part of the femoral neck have been associated with femoral component failure. The hypotheses of this study were that placement of a femoral resurfacing component alters femoral n...
a microprocessor system capable of averaging 256 QRS complexes to reduce noise. The QRS was digitally filtered and the root-mean-square (RMS) voltage of the residual (80-300 Hz) signal computed. High-frequency RMS values were significantly (p < 0.01) greater in leads II, III and aV7 in normal subjects (n = 12) than in patients with inferior infarction (n = 12). Similarly, high-frequency RMS val...
