In an example, when the QRS duration exceeds a threshold duration, and the RV activation time does not exceed a second threshold duration, an indication of a cardiac conduction dysfunction can be provided, such as for discriminating between left bundle branch block and right bundle branch block....
Myocardial perfusion scintigraphy often reveals perfusion defects in septal/ anterior segments of left ventricular myocardium in patients with left bundle branch block (LBBB) even in the absence of coronary artery disease (CAD). This study investigated whether gated single photon emission computed tomograp...
Individuals were excluded at the study level for: prevalent myocardial infarction or heart failure, pregnancy at the time of recruitment, implantation of a pacemaker or implantable cardiac defibrillator, QRS duration >120 ms, or right or left bundle branch block or atrial fibrillation on ECG. ...
Right bundle branch block, persistent ST segment elevation and sudden cardiac death: a distinct clinical and electrocardiographic syndrome. A multicenter report. J. Am. Coll. Cardiol. 20, 1391–1396 (1992). Article CAS PubMed Google Scholar Priori, S. G. et al. 2015 ESC Guidelines for the...
The VT QRS was relatively narrow with an incomplete right bundle branch block morphology and inferior frontal axis. Transthoracic echocardiography confirmed normal left ventricular systolic function and the absence of structural heart diseases. Mapping catheters were introduced via venous access to the ...
In the subgroup of patients with cardiac disease with normal left ventricular ejection fraction, the occurrence of syncope was less frequent, and the number of arrhythmic events was no greater in these patients. Implantable loop recorder is a useful diagnostic tool for recurrent syncope of unknown ...

In an example, when the QRS duration exceeds a threshold duration, and the RV activation time does not exceed a second threshold duration, an indication of a cardiac conduction dysfunction can be provided, such as for discriminating between left bundle branch block and right bundle branch block....
Using forward stepwise regression followed by a bootstrapping analysis, the final model included: left ventricular end-diastolic diameter ≥6.5 cm (OR 3.23 [1.72–6.06 g], P < 0.001), the presence of a non-left bundle branch block (non-LBBB) morphology (OR 2.18 [1.18–4.04, P = 0.013]...
