“…En concordancia con nuestros hallazgos, otros autores han publicado frecuencias cardíacas promedio entre 80 y 85 lpm. (6,9) El aumento en la frecuencia cardíaca es uno de los mecanismos utilizados para incrementar el gasto cardíaco.

“…La presencia de una onda q en DIII es aceptada como normal en la mayoría de las personas, en ausencia de cambios acompañantes en otras derivaciones contiguas. En nuestro estudio observamos que entre el 30% y el 40% de las pacientes tenían onda q en cara inferior, a veces acompañada de cambios en la onda T. Esto también fue observado por Chaudhary et al (9),quienes informaron que hasta el 30% de las pacientes presentaban ondas q en DIII, DII y aVF. Similares hallazgos reportaron Sunitha et al ( 5) La presencia de ondas q en las derivaciones precordiales, desde V3 hasta V6, ha sido descrita por ambos autores, pero con frecuencias dispares, entre el 10% y el 60%.…”
