An integrated vectorcardiogram (VCG) device having 3 pairs of electrodes placed in three orthogonal directions with the capability to continuously measure the electrical activity of the heart. All of the electrode pairs may be contained within a single miniaturized housing thereby eliminating the need for cumbersome wires required with current 12-lead ECG systems, while providing the same amount and quality of information as the 12-lead ECG system. The integrated VCG device also includes a communications function to allow the data collected by the electrodes to be transmitted wirelessly to a remote device, such as a pacemaker, to control its function or to a remote monitoring station for continuous real-time patient monitoring.

Described herein are systems, devices and methods for guiding placement of electrodes, and particularly ECG electrodes on a patient. A picture of the patient's body the patient can be analyzed to determine where on the patient's body to place electrodes according to a predetermined, conventional or standard placement pattern. The methods, devices and systems may then guide a user in positioning or correcting the position of electrodes on the patient. For example, an image of the patient may be provided showing the correct position of the electrodes, which may act as a patient-specific map or guide. The electrode placement positions can correspond to conventional or standard 12-lead ECG electrode positions.

A multi-function health monitor is capable of performing a resting 12-lead ECG test, an ECG stress test, a 24-hour holter monitor evaluation and or a 30-day MCT monitoring. Using only 3 electrodes, the multifunction health monitor derives 6 channels (Limb leads & Augmented leads) of data with the noise cancellation (ground) effect of a virtual dynamic RL electrode. An electrode resistivity measurement system quantifies and may compensate for increasing resistance the electrodes and the patient that results from the length of time the electrodes are installed on a patient. The multi-function health monitor can provide data analysis through the gate array as the data is acquired. Data may also be stored for remote analysis as well as for transmission to remote stations upon occurrence of one or more threshold events. Parameters for threshold events may be adjusted remotely to obviate the need for a patient to travel for system adjustment.

The invention discloses an automatic detection method of myocardial infarction based on lead fusion deep neural network. The automatic detection method includes the following steps: 1) generating 12-lead ECG signal samples by intercepting a single heart beat; 2) building a 12-lead ECG signal cnvolutional neural network model; 3) training parameters of the convolutional neural network; and (4) carrying out automatic recognition on test set samples; and inputting the divided test set samples into the convolutional neural network and carrying out running to obtain the 2-dimensional predicted value vector output corresponding to the test set samples, generating the 2-dimensional label vector using the one-hot coding method for labels of the test set samples, comparing the output predicted values with the labels of the test set samples to check the correctness of the classification, and judging the performance of the model by the classification result y_pred. The method achieves relativelyhigh accuracy in the recognition of multi-lead ECG signals. furthermore, the accuracy of the method in the recognition of heart beat for myocardial infarction can reach 99.51%.
