ECG showed normal sinus rhythm with left
bundle branch block and wide QRS [Figure 2].
In the current case report, we present a patient who was diagnosed with subarachnoid hemorrhage and had left
bundle branch block (LBBB).
The ECG recordings of the groups were compared based on the frequencies of the right
bundle branch block, left
bundle branch block, left anterior hemi block (LAH), left posterior hemi block (LPH), first-degree atrioventricular (AV) block, unifascicular block, bifascicular block, trifascicular block, and fragmented QRS.
Objective: To determine the frequency of intraventricular dyssynchrony among patients with left
bundle branch block.
Like most VSD closures, his almost certainly was performed through a right ventriculotomy, and all of his electrocardiograms (ECGs) demonstrated the resulting right
bundle branch block (Figure 1).
Electrocardiogram (ECG) showed right axis deviation, right
bundle branch block (RBBB), right ventricular hypertrophy and atrial fibrillation.
The ECG was assessed for heart rate (HR), rhythm, S wave in lead I,SIQIIITIII pattern, Q wave /T wave inversion in lead III, incomplete or complete right
bundle branch block (RBBB), ST-segment elevations/depressions, and T-wave inversions (TWI).
In patients with acute myocardial infarction, prevalence of right and left
bundle branch block are similar.
I degree AV block indicates by prolonged PR interval, with all P waves having an associated QRS complex, II degree AV block denotes by some P waves being blocked, while others are conducted and right
bundle branch block indicates by deep S wave.
