Right atrium hypertrophy

ECG in left bundle branch block is characterized: - the QRS interval is 0,12 sec in duration;

-wide and deformed QRS has the form of qR in I, II, V5- 6; rS in III,

aVF, V1-2 (the shape of the ventricular complexes resembles that of right

ventricular extrasystoles);

-disconcordance of ST, T and the main wave of QRS; - levogram.
