Los propósitos de este trabajo fueron: primero, evaluar el grado con el cual el tiempo de tránsito del pulso (TTP) covería con la presión sistólica; segundo, estimar la influencia del período de preeyección sobre el TTP; tercero, probar un índice de reactividad en la presión arterial, y cuarto, estudiar el decremento en la actividad cardiovascular a lo largo del tiempo.
Los resultados revelan una alta correlación entre el TTP y la presión sistólica (¯=—. 866), aunque el TTP probablemente no sólo refleje cambios de la presión arterial, sino también del período de preeyección.
La respuesta ante una tarea de aritmética mental, en contraste con una linea base de relajación, se mostró como un buen índice de la reactividad en la presión sistólica.
El cuarto propósito no pudo realizarse por no producirse el decremento esperado en la actividad cardiovascular.
