The present invention relates to a cardiovascular diagnostic system which enables early detection of cardiovascular diseases and defines their causes. Unlike known electrocardiographs, the cardiovascular diagnosis system can further measure elastic coefficient of blood vessels (the degree of arteriosclerosis), blood vessel compliance, blood flow, and blood flow resistance and velocity in blood vessel branches of the right and left coronary arteries. The elastic coefficient shows organic changes to blood vessels. The compliance shows organic and functional changes of blood vessels simultaneously. The blood flow shows blood flow resistance.

A method of determining an ischemic event includes the steps of: monitoring and storing an initial electrocardiogram vector signal (x, y, z) of a known non-ischemic condition over the QRS, ST and T wave intervals; calculating and storing a J-point of the vector signal and a maximum magnitude of a signal level over the T wave interval; monitoring a subsequent electrocardiogram vector signal over the QRS, ST and T wave intervals; measuring and storing the magnitude (Mag.) of the vector difference between a subsequent vector signal and the initial vector signal; measuring and storing the angle (Ang.) difference between a subsequent vector and the initial vector at points; regressing a line from points about 25 milliseconds prior to the J point and about 60 milliseconds after the J-point and determining the slope of the regression line and the deviation of the angle difference of the regression line; regressing a line from points about 100 milliseconds prior to the maximum magnitude of the signal level over the T wave interval and determining the slope of the regressing line and the deviation of the angle difference of the regression line; and comparing the slope and deviation of the lines from the J point and the T wave interval to a set of known values to determine the presence of an ischemic event.

The invention relates to a three-dimension picture electrocardiograph, and relative application, wherein it has 16 electrode lines parallel input 5 channels Einthoven-Goldberger-Wilson and Frank guide system; the Frank electrocardiograph collects electrocardiograph signal to be treated by computer, computer assist design, to realize multi-dimension, synchronous, and real-time conversation; storing at 24h, synchronizing 1-78 guides or selectively washing electrocardiograph; generating database, 12 electrocardiographs, orthogonal electrocardiograph, vector electrocardiograph, etc.

The invention relates to a high-speed rail dispatcher stress detection method based on multi-physiological signal multi-model interaction, which adopts an electroencephalogram signal collection device, an electrocardiogram collection device, and an eye movement collection device to jointly acquire corresponding physiological signals for information collection and processing to The stress state of the tested high-speed rail dispatcher is judged. After feature selection, model training and information fusion processing, the EEG, Information fusion of ECG and eye movement recognition results to extract better EEG, ECG and eye movement recognition results, and then fuse EEG, ECG and eye movement recognition results, and finally obtain the fusion feature recognition results quickly and effectively Judging the stress state of high-speed rail dispatchers.

The invention provides an anti-interference electrocardiogram inspection device, which relates to the field of electrocardiograph, and solves the problem that when the existing electrocardiogram inspection device is in use, the sandpaper cannot be automatically attached to the skin to remove the stratum corneum, and the sandpapers of different models and sizes cannot be fixed. The problem includes the main body; the main body is the body of the electrocardiogram inspection device, and the main body is a T-shaped structure, and supports are installed at both ends of the bottom of the main body. When the device is in use, insert the sandpaper into the bottom groove, and then the pressing plate receives the spring force to move downward, so that the rubber contact block can press and fix both ends of the sandpaper, and then pull the control rod to move up, so that the rod can be in the The inside of the inner groove moves, and then pulls the block to retract, so that the side piece can be released from the limit, push the bottom of the side piece and the sandpaper to move down, so that the sandpaper can automatically close to the chest and abdomen of the human body, and then control the movement of the main body, so that the sandpaper can be moved. Easily remove cuticles.

The invention relates to a medical device, in particular to a preparation device for an electrocardiograph fixing plate for a cardiology department. According to the preparation device for the electrocardiograph fixing plate for the cardiology department, raw materials of the electrocardiograph fixing plate can be cut and perforated through a cutting and perforating device, when the raw materialsof the electrocardiograph fixing plate are cut through the cutting and perforating device, plates with different widths and different thicknesses can be cut; in the case of the cutting and perforatingdevice, perforating needles of different specifications can be conveniently replaced so that holes of different specifications can be prepared conveniently; vibration generated by the preparation device can be reduced through the buffering device, the preparation device comprises the cutting and perforating device, the buffering device, a support combination, a middle-end connecting rod and an inner-end push spring I, a cutting motor is driven through an inner-end connecting terminal to move, so that the cutting motor and a cutting saw do left-and-right reciprocating motion, the cutting saw is in contact with the raw materials of the electrocardiograph fixing plate, so that cutting of the raw materials of the electrocardiograph fixing plate is completed; and a conveying roller V, a conveying roller IV, a conveying roller I, a conveying roller II and a conveying roller III rotate, so that raw material conveying of the electrocardiograph fixing plate is completed.
