![]() ![]() ![]() Se incluyó a 196 pacientes seguidos durante una mediana de 30,1 meses. Se clasificó a los pacientes en tres subgrupos: superrespondedores, respondedores y no respondedores. Se comparó la incidencia de arritmias ventriculares en pacientes portadores de desfibrilador automático implantable con función de resincronización cardiaca, según el grado de respuesta ecocardiográfica a la resincronización. Sobre su papel en la reducción de arritmias ventriculares, hay más discusión. La terapia de resincronización cardiaca se asocia a mejora de la calidad de vida y reducción de la morbimortalidad de los pacientes con disfunción ventricular grave y QRS ancho. Despite this, arrhythmic episodes do not completely disappear in this subgroup. The patients classified as super-responders to cardiac resynchronization therapy had a significant reduction in incidence of ventricular arrhythmias by comparison with the other patients. 049) and treatment with amiodarone (odds ratio = 2.47 95% confidence interval, 1.03-5.91 P =. In multivariate analysis, the only independent predictors of the appearance of ventricular arrhythmias were secondary–prevention device implantation (odds ratio = 4.04 95% confidence interval, 1.52-10.75 P =. We recorded the presence of ventricular arrhythmias in 37 patients (18.8%) 3 patients (5.9%) in the super-responder group had ventricular arrhythmias vs 14 (22.2%) among the responders and 20 (24.4%) in the group of nonresponders ( P =. We included 196 patients who were followed up for a median 30.1 months. Patients were classified in 3 subgroups super-responders, responders, and nonresponders. We compared the incidence of ventricular arrhythmias in patients who were undergoing cardiac resynchronization therapy with an implantable cardioverter-defibrillator in terms of the degree of echocardiographic response to resynchronization. However, its role in the reduction of ventricular arrhythmias is more controversial. The ECG in Acute MI.Cardiac resynchronization therapy is associated with improved quality of life and reduced morbidity and mortality in patients with severe ventricular dysfunction and wide QRS.

Not due to any of the causes above - Before making this diagnosis, be sure to check the serum potassium level and scrutinise the ECG for any signs of TCA toxicity.
