Significance of perfusion defects on dipyridamole thallium cardiac SPECT in patients with left
bundle branch block.
We excluded patients with complete
bundle branch block, intra-ventricular conduction delay, and patients with permanent pacemakers in our study.
Intermediate pretest probability patients with left
bundle branch block require myocardial perfusion imaging
Electrophysiological study: induction of another type of VT morphology (monomorphic VT with aspect of right
bundle branch block, 200 bpm, superior axe--possible localization in the postero-lateral wall of the left ventricle)
Pinski, "Acute Myocardial Infarction and Complete
Bundle Branch Block A Hospital Admission Clinical Characteristics and Outcome in the Thrombolytic Era." (16) The incidence of hypotension in AV blocks is 38.8%, whereas hypotension in AV block seen in 38.8% cases and intraventricular block is 92%.
Left
bundle branch block as a risk factor for progression to heart failure.
Conclusion: The incidence of Intraventricular dyssynchrony is high among patients with heart failure and left
bundle branch block.
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.
Right
bundle branch block, persistent ST segment elevation and sudden cardiac death: a distinct clinical and electrocardiographic syndrome.
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.
