A listening system (501, 601) comprising: an aortic pressure sensor (508, 608) configured to measure an individual's aortic blood pressure and provide a signal representing a value of aortic blood pressure measured by a pressure sensor internal distal (509, 609) configured to measure the distal blood pressure of the individual and provide a signal that represents a measured distal blood pressure value; a receiver (504, 604) configured to receive both a signal representing the measured aortic blood pressure and a signal representing the value of the measured distal blood pressure, the receiver comprising a viewer configured to display data that is based on at least the value of the measured aortic blood pressure and the value of the measured distal blood pressure; wherein the system further comprises: a communication interface (507, 607) configured to be positioned along a wired aortic channel (503, 603) between said aortic pressure sensor (508, 608) and a monitoring device ( 505, 605), wherein said communication interface (507, 607) comprises a high impedance listening connector to said wired aortic channel (503, 603), and the communication interface (507, 607) is further configured to (i) listening through said listening connector the signal in the signal representing the measured aortic blood pressure value sent along said wired aortic channel (503, 603) without altering the measured aortic blood pressure value , and (ii) sending a signal that represents the measured aortic blood pressure value of said receiver (504, 604) through a wireless connection between said communication interface (507, 607) and said receiver (504, 604) unchanged the measured aortic blood pressure value.Un sistema de escucha (501, 601) que comprende: un sensor de presión aórtica (508, 608) configurado para medir la presión sanguínea aórtica de un individuo y proporcionar una señal que representa un valor de la presión sanguínea aórtica medida un sensor de presión distal interno (509, 609) c
