Posibilidades y realidades de la estimulación permanente del haz de His / The potential and reality of permanent his bundle pacing

RESUMEN

La estimulación apexiana puede ser perjudicial. Intentamos averiguar cuántos pacientes propuestos para estimulación cardiaca definitiva podrían ser estimulados permanentemente en el haz de His y en cuántos se consigue. La totalidad de los bloqueos suprahisianos y la mayoría de los considerados «infrahisianos» (71,4%) se corrigen con la estimulación del His, pero sólo se consigue permanentemente en el 55% de los intentos y en el 35,4% de todos los casos posibles (AU)

ABSTRACT

Right ventricular apex pacing can have deleterious effects. Our aims were to investigate how many patients referred for permanent pacing were suitable candidates for permanent His bundle pacing, and to determine the proportion in whom such pacing was successful. All cases of suprahisian block and most cases of infrahisian block (71.4%) were corrected by temporary His bundle pacing. However, permanent His bundle pacing was achieved in only 55% of cases in which it was attempted, and in only 35.4% of all possible cases (AU)
