UNLABELLED The abnormal development of the tricuspid valve in patients with Ebstein's anomaly results in several activation abnormalities including delayed intraatrial conduction, right bundle branch block (RBBB), and ventricular preexcitation. The aim of the present study was to define the ECG characteristics before and after ablation of an accessory A-V pathway (AP) in patients with Ebstein's anomaly. METHODS A series of 226 consecutive patients with Ebstein's anomaly was studied. Sixty-four patients (28%) had documented tachycardia. Thirty-three patients with recurrent tachycardia were found to have a single right-sided AP that was successfully ablated (study group). Thirty patients without tachycardia served as the control group. RESULTS Only 21 of 33 patients (62%) had a typical ECG pattern of preexcitation. In addition, none of the patients had an ECG pattern of RBBB during sinus rhythm. In contrast, 28 of 30 (93%) patients in the control group had RBBB (P < 0.001). Radiofrequency catheter ablation resulted in appearance of RBBB in 31 of 33 (94%) patients. The absence of RBBB in patients with Ebstein's anomaly and recurrent tachycardia had a 98% sensitivity and 92% specificity for the diagnosis of an AP. The positive predictive value was 91% (0.77, 0.97 CI 95%) and the negative predictive value was 98% (0.85, 0.99 CI 95%). CONCLUSION One-third of patients with Ebstein's anomaly and symptomatic tachyarrhythmias have minimal or absent ECG features of ventricular preexcitation. In these patients, the absence of RBBB pattern is a strong predictor of an AP.

Se considera que el sobrepeso es un factor de riesgo importante para la salud, por lo cual como profesionales de la salud se debe tomar conciencia de la importancia de alcanzar un bienestar saludable tanto físico como psíquico mejorando la calidad de vida mediante el autocuidado de lo contrario se obtendrá como resultado, consecuencias importantes, que llevan a múltiples enfermedades. Estas consecuencias comienzan a provocar indudablemente un ausentismo laboral, como así también mala predisposición en el trabajo y agotamiento físico, entre otras dificultades. El presente trabajo tiene como objetivos: determinar las causas del aumento de peso y cómo influye en el rendimiento laboral del personal de enfermería del Hospital Perrupato; identificar la población de enfermería con sobrepeso; demostrar cómo influye el aumento de peso en el rendimiento laboral e identificar el ausentismo laboral del personal de enfermería, por problemas de salud relacionadas con el sobrepeso.
