2. the device used to draw cardiac electrical current maps only supports the top of the chest, without the use of limbs cable or conductive gel. The instrument shows that two orthogonal derivatives and their corresponding VCG (vector antennae) occur simultaneously in cardiac activity. It differs from 12 electrocardiogram (ECG) separators, which use bipolar electrodes for pre-ordering (ECG uses unipolar electrodes), and can detect invisible changes in traditional systems. Similarly,It can regenerate 12 separators from two registries, but its accuracy has not been clinically validated as an alternative to preliminary screening methods. In addition, through the study of different parts of the thoracic cavity, we can find the undetectable electrical interference of ECG. In some locations (Lewis derivation), P band can be well recorded, which is very useful for heart rate assessment of width. It can also detect Delta waves.D psillon (right ventricular arrhythmia) and Osborn wave (hypothermia).
