El ápex de ventrículo derecho (AVD) es el sitio convencional de estimulación cardiaca; sin embargo, no ha conseguido un patrón de activación y sincronía fisiológico. La evidencia de su efecto deletéreo ha hecho que se cuestione su práctica tradicional, por lo que nace el interés de búsqueda de sitios alternativos. El tracto de salida de ventrículo derecho (TSVD) ha demostrado ser un lugar adecuado para estimulación, sin diferencias entre umbrales de estimulación entre ambos sitios. Objetivo: Comparar los resultados del implante a nivel del ápex con los del implante en tracto de salida de ventrículo derecho. Material y métodos: Estudio descriptivo, comparativo de serie de casos retrospectivo. Se incluyeron 54 pacientes con implante de marcapaso entre 2010 y 2011. Se tomaron en cuenta datos clínicos, datos del implante propiamente dicho y sus complicaciones. Resultados: L...

Introduction: Carrion’s disease is considered a re-emerging disease in Peru, and it leads to several non-infectious and infectious complications.Objectives: To assess cardiovascular complications (CC) during the acute phase of this disease.Methods: An observational study was conducted at Cayetano Heredia Hospital (HNCH) from 1987 to 2007. Adult patients with a confirmed diagnosis of Bartonellosis were included.  Results: 68 patients were included (52 males, mean age 25,7 years). No one had prior cardiovascular disease. Main clinical findings were: fever (99%), hepatomegaly (79%), jaundice (74%), tachycardia (74%), tachypnea (71%), systolic murmur (68%), dyspnea (62%), hepatojugular reflux (19%) and jugular ingurgitation (15%). Sixty-four chest X-ray films showed the following findings: 44% cardiomegaly, 20% pulmonary congestion, and 16% pleural effusion. Transth...
