The present invention relates to an apparatus for continuously and automatically measuring a pulse wave by a non-invasive method to know the state of a cardiovascular system, and a method for measuring blood pressure. The apparatus for continuously and automatically measuring a pulse wave according to one embodiment of the present invention comprises: an integrated measurement module comprising an electrocardiogram measurement portion for measuring the electrocardiogram of a subject, a bioelectrical impedance measurement portion for measuring the bioelectrical impedance of the subject by a potential difference, a heart sound measurement portion for measuring the heart sound of the subject, and a controller for measuring and controlling the state of the cardiovascular system of the subject on the basis of a pulse transit time (PTT) calculated by the electrocardiogram signal measured at the electrocardiogram measurement portion, the bioelectrical impedance signal measured at the bioelectrical impedance measurement portion, and the heart sound signal measured at the heart sound measurement portion a first communication power module comprising a first wireless communication portion for wirelessly sending and receiving the information of the integrated measurement module and the information of an external terminal, which is electrically connected to the integrated measurement module, and a first power supply portion for supplying power to the first communication power module and the measurement module and a bio-measurement pad in which the integrated measurement module and the first communication power module are placed, and which comprises a bio-electrode electrically connected to the bioelectrical impedance measurement portion. Therefore, it is possible to easily and accurately measure the state of a cardiovascular system.Linvention concerne un appareil permettant de mesurer une onde de pouls de manière continue et automatique par une méthode non invasive pour connaîtr
