[The problems of the modern electrocardiography (to the 100th anniversary of electrocardiography, 1903-2003)].

Elucidated in the paper are the key issues of modern electrocardiography (ECG). The negative results of large-scale use of automated ECG interpretation programs are under discussion. The possibility of removing the analogue filters from the electrophysiological apparatus and replacing them with the digital signal processing equipment is contemplated. The modern ECG examinations can not exist without simple automation the program security of information processing. The results of introducing the or apparatus-program complexes (APC) into practice as auxiliary analysis instruments in ECG are analyzed. The effects of APC introduction into daily ECG practice are shown to be advantageous. Finally, there is an analysis of issues related with global computerization in clinical examinations.

The value of electrocardiography in patients with right ventricular endocardial pacemakers in the diagnosis of left ventricular hypertrophy: a correlative study of pace electrocardiography and left ventricular mass derived from M-mode echocardiography.

This study evaluated 51 patients with permanent apical right ventricular endocardial pacemakers. The assessment of the diagnostic value of pace electrocardiograms for the determination of left ventricular hypertrophy revealed specificity of 94% and sensitivity of 66%, applying a new parameter: RL1 + SV3 greater than or equal to 30 mm. The application of this criterion in the interpretation of pace electrocardiograms correlated well with values for the left ventricular mass derived from M-mode echocardiograms (r = 0.644, P less than 0.0001).
