El pulso ha sido uno de los elementos que fué primeramente observado en los viajes a las grandes alturas. Se ha pretendido establecer una relación entre la altura y la frecuencia del pulso mientras este fué estudiado durante el viaje. En la actualidad - en los casos de ascensiones sin esfuerzo o aeroplano - está demostrado que tal hecho no ocurre, sino en determinadas condiciones de rarefacción del aire. Podemos afirmar, como resultado de nuestras observaciones, que esta frecuencia es relativamente moderada y que únicamente cuando se presentan signos de Soroche se rompe el ritmo normal para aparecer una taquicardia más o menos intensa.

In the previous communication we had necessarily refer to the performance of the heart against the effort to determine the frequency characteristics, shape, stability, etc., constituting man's pulse rate of the Andes. Indeed, we have noted the frequency of bradycardic and ortocárdicas reactions which are undoubtedly the best example of the physiological assessment of the Andean heart. So we said that the law of the Andean heart versus moderate or large effort, it is not a straight line as they occur at sea level - equal acceleration effort - but at the expense of the creek ortobradicárdicas reactions slowed to acceleration.
