PURPOSE:To grasp ST change which is of importance for diagnosis and remedy of diseases, in particular attack with ischemic chest pain, by furnishing a means (RAM) to update and store the electrocardiometric data till three min ago, and reading and displaying the stored data out of the RAM with operation in conformity to a given command. CONSTITUTION:A portable electrocardiograph is equipped with an electrocardiometric amplifier 2 to amplify electrocardiometric signals, an A/D converter 3 to convert the amplified analog signals into digital electrocardiometric data, a CPU 4. a RAM 6 to accommodate the electrocardiometric data, a liquid crystal display device 8, and touch keys 9 to make entry according to various command operations. The RAM 6 updates and stores the data till at least three min ago at all trimes, while the touch keys 9 read the stored data out of the RAM 6 in conformity to a certain command operation and displays it on the liquid crystal display device 8. Thereby ST change of importance for diagnosis and remedy for attack with chest pain can be grasped while the electrocardio-waveforms are displayed on a monitor screen continuously. |
