An embodiment of the present invention relates to a mobile communications terminal having a defibrillation function and an emergency patient saving system using the same. The mobile communications terminal is combined with the defibrillation function so that a patient who carries the mobile terminal having a defibrillation function can use the defibrillation function by him/herself in emergency. To this end, an embodiment of the present invention provides the mobile communications terminal having a defibrillation function including: a defibrillation execution unit that includes a connector arranged on one end portion thereof and at least one electrode pad arranged on the other end portion thereof, senses electrocardiogram of a user, and transmits defibrillation shock； a defibrillation generation unit which receives an electrocardiogram signal when connected to a connector, and generates the defibrillation shock； a first power supply unit which supplies power to the defibrillation execution unit and the defibrillation generation unit； a display unit which is linked to the defibrillation generation unit and displays a waveform of the electrocardiogram； a communications interface unit for transmitting and receiving data to and from an external device； and a main control unit. The main control unit: includes a defibrillation application installed thereon； automatically executes the defibrillation application when the electrode pad is connected to the connector； supplies power to a defibrillation execution unit and the defibrillation generation unit through a first power supply unit by execution of the defibrillation application； analyzes whether the electrocardiogram sensed by the defibrillation execution unit is abnormal； applies a control signal to make the defibrillation generation unit to generate the defibrillation shock when the electrocardiogram is abnormal； and controls an emergency signal to be transmitted through the communications interface unit to the extern
