Abstract

The present invention features that the lead method of synchronous 18-lead electrocardiogram converted in corrected orthogonal electrocardiogram mode includes back left deriving V7, V8 and V9 as the three lead axes to reflect the back wall of the left ventricle with V6 lead as base point, right deriving V3R, V4R and V5R as the three lead axes to reflect the right ventricle with V1 lead as base point, and synchronous displaying of the six lead axes and 12 conventional lead axes. The expanded lead method of synchronous 21 leads includes back left deriving V7, V8 and V9 as the three lead axes on the basis of V5 lead axis. The lead method including converting the inclined angles in orthogonal electrocardiogram mode with right and left side correction and multiple bedding plane electrocardiogram lead containing up and down whole angles is the combined application of lateral electrocardiogram and transverse plane / frontal plane electrocardiogram.

Description

technical field

[0001] The invention relates to a lead method for electrocardiogram detection instruments used in clinical medicine, especially a hardware system for electrocardiogram amplification in the instrument, which is realized by computer software, and the operation deduced by mathematical derivation method is extremely simple , Only seven body surface electrodes can be used to obtain almost all ECG leads, and a large amount of information can be converted into multiple synchronous ECG lead methods in the form of corrected orthogonal ECG. Background technique

[0002] The technical theoretical basis of the present invention originates from the basic theory of ECG vector-orthogonal electrocardiogram and secondary projection of clinical electrocardiogram.

[0003] The ECG re-projection theory is the most basic theory of ECG generation, and it is the teaching theory used to explain the generation of ECG in the field of ECG. Its theoretical basis has been recognized by ...
