The aim of this study is to review the long-term outcomes of a series of patients with ventricular tachyarrhythmias who commenced empiric treatment with either amiodarone or sotalol in the period before electrophysiologic studies were used routinely at our institution. We compared these two class III dru...
Programmed electrical stimulation (PES), angiographic studies, Holter recording, 12-lead ECG and signal averaged ECG (SAECG, n=63) were performed in 109 consecutive patients with a prior Q-wave myocardial infarction (MI). Sixty-five patients (59 por cento) had TMI-class ) or 1 antegrade perfusion without...
We report our experience regarding definitive treatment for concurrent atrioventricular reciprocating and AV node reentry tachycardia in 184 consecutive patients undergoing accessory connection ablation. 18 patients also had inducible sustained AV node reentry tachycardia. Sixteen out of 18 patients unde...
La taquicardia incesante puede ser causada por diferentes mecanismos electrofisiológicos. Desde 1986, hemos estudiado 13 pacientes con taquicardia incesante, 9 hombres y 4 mujeres (edad promedio 35a). Diez pacientes habÃan recibido múltiples antiarrÃtmicos y 4 habÃan desarrollado insuficiencia cardÃ...
Se realizó un estudio experiemtal comparativo para determinar la eficacia del esmolol y afentanil en el control de la tensión arterial y la frecuencia cardiaca durante la laringoscopÃa e intubación en 30 pacientes sometidos a cirugÃa electiva bajo anestesia general inhalatoria. Previamente a la lari...
