Left ventricular activation time in left ventricular hypertrophy and in left bundle-branch block.
Simultaneous tracings of right and left ventricular leads were taken in 6 dogs with experimentally produced left bundle-branch block, and in 30 clinical cases of left ventricular hypertrophy. In the experimental study it was found that the initial phase of the QRS complex in the right epicardial lead did not change its configuration or its duration after the production of left bundle-branch blo...
متن کاملLeft ventricular hypertrophy in presence of complete left bundle-branch block.
Electrocardiograms of 2500 consecutive patients who died in hospital were reviewed in order to study the relation ofcomplete left bundle-branch block to pathological determinants ofanatomical left ventricular hypertrophy. Of these, 43 patients demonstrated complete left bundle-branch block and all but two had anatomical left ventricular hypertrophy at necropsy. -Mean values of total heart weigh...
متن کاملElectrocardiographic criteria of left ventricular hypertrophy in left bundle-branch block.
In order to determine whether the electrocardiographic criteria of left ventricular hypertrophy apply in the presence of left bundle-branch block we studied 79 cases of intermittent left bundle-branch block and compared the QRS voltage and axis before and after its onset. Cases of incomplete left bundle-branch block were excluded. There was a statistically significant correlation between pre- a...
متن کاملLeft bundle branch block and left ventricular hypertrophy: electrocardiographic-pathologic correlations.
A clinical-pathologic study was made of 50 patients with complete left bundle branch block who had postmortem examinations performed at three Salt Lake City hospitals. Forty (80 percent) were found to have left ventricular hypertrophy as determined from measured left ventricular wall thickow but only 14 had electrocardiographic evidence of this while two of the ten patients without left ventric...
متن کاملVariable left ventricular activation pattern in patients with heart failure and left bundle branch block.
OBJECTIVE To determine the left ventricular (LV) activation pattern in patients with chronic heart failure and left bundle branch block (LBBB) on ECG. DESIGN Prospective study. SETTING Tertiary cardiology referral centre in Hong Kong. PATIENTS Seven patients with LV ejection fraction < 35% and typical LBBB on ECG with QRS duration > or = 130 ms were recruited. Five of them had non-ischaem...
