Differentiation of intraventricular blocks by means of electrocardiography and vectorcardiography

: The examination was conducted in 270 patients with ischaemic heart disease and signs of intraventricular conductivity disorders. The most demonstrative signs were singled out in ECG and VCG recordings that permit one to differentiate unifascicular, bi- and trifascicular blocks. Emphasis is made on the diagnosis of focal changes in the myocardium in the presence of excitation conduction disorders in the above mentioned branches of the bundle of His.
