Risk stratification and prognostic assessment by myocardial perfusion-gated SPECT in patients with left bundle-branch block
and low-intermediate cardiac risk.
In addition to these abnormalities, late risers were also prone to other diseases like Wolf-Parkinson-White-Syndrome32 and right and left bundle-branch blocks
(RBBB and LBBB)33.
The clinical suspicion of LDAC is alerted in patients who present ventricular arrhythmias of RBBB and left bundle-branch block
type and unexplained T-wave inversion in inferolateral leads.
Kontos MC, Aziz HA, Chau VQ, Roberts CS, Ornato JP, Vetrovec GW (2011) Outcomes in patients with chronicity of left bundle-branch block
with possible acute myocardial infarction.
Electrocardiogram (ECG) revealed sinus rhythm, normal axis, prolonged PR interval and complete left bundle-branch block
(LBBB) with QRS duration of 160 ms.
Only three minor heart conduction disorders were noticed, including two incomplete right bundle-branch blocks
and one complete left bundle-branch block

ST segment depression can be an indication of myocardial ischemia, ventricular hypertrophy, bundle-branch block
, or hypokalemia, or may result from digitalis administration.
Of these four, the ECGs of two patients normalized, one 17-year-old female remained with atrioventricular (AV) dissociation and intermittent left bundle-branch block
, and one 15-year-old female developed right bundle-branch block
plus fascicular left bundle-branch block
in middle-aged men: risk of complications and death over 28 years The Primary Prevention Study in Goteborg, Sweden.
