The invention relates to the technical field of counterpulsation control, and discloses a core algorithm for synchronously applying pressure to external counterpulsation equipment in combination with electrocardio and pulse information, which comprises the following steps of: S1, collecting an electrocardio signal and a pulse signal of a user, synchronously processing the electrocardio signal and the pulse signal, determining a systolic period and a diastolic period of a heart, and acquiring a pulse signal of the user; s2, according to the synchronous processing result of the electrocardiosignal and the pulse signal, the actual starting time of pressure application of the external counterpulsation equipment is determined, the reaction time difference between the systolic period and the diastolic period of the heart and the pressure sensor is obtained, and according to the reaction time difference threshold value, the actual starting time is reset and corrected; a pressure sensor is arranged on a counterpulsat
