Spatial vector cardiography: From origins to the present day. A review

Терапевтический архив
Vectorcardiography (VCG) originated back in 1887 due to the discovery of the dipole theory of the heart electric vector by Augustus D. Waller. Despite the fact that the idea of constructing an electric vector of the heart quickly gained appreciation ...

ISE/ISHNE expert consensus statement on the ECG diagnosis of left ventricular hypertrophy: The change of the paradigm

Annals of Noninvasive Electrocardiology, Volume 29, Issue 1, January 2024.
Central illustration: The new ECG‐LVH paradigm. LAD: left axis deviation, LAFB: left anterior fascicular block, LBBB: left bundle branch block. Abstract The ECG diagnosis of LVH is predominantly based on the QRS voltage criteria. The classical paradigm postulates that the increased left ventricular mass generates a stronger electrical field, increasing
