The cardiostimulation monitor utilizes variable speed of writing and reading from semiconductor memory for achieving time transformation enabling synchronous displaying of the shape of cardiostimulation impulse by means of a cardiomonitor. The source of the signal is connected to a rectifier (1) and simultaneously to an analogue memory input (6). The output of the rectifier (1) is connected with the input of a comparator (2), whose output is connected to the input of the first monostable circuit (3), whose output is connected to the input of the second monostable circuit (4) and simultaneously it is connected to the input of the comparator (2). The output of the second monostable circuit (4) is connected to the input of the circuit (5), whose output is connected with the memory (6). The analogue output of the memory (6) is lead to a display unit (7).<IMAGE>
