The image below shows the typical findings of a left bundle branch block in the precordial ECG leads. Note: If the QRS duration is 100 to 119 ms with criteria 2, 3 and 4 of the above, an ...

However, unlike in the presence of a left bundle branch block, myocardial ischemia and infarction can easily be detected on ECG when a RBBB is present. Below is an ECG displaying a right bundle ...

In fact, up to 60% of athletes demonstrate ECG changes (in isolation or in combination) such as sinus bradycardia, sinus arrhythmia, first-degree atrioventricular (AV) block, early repolarisation, ...

VPDs with very short coupling intervals developing during an acute stage of myocardial infarction would predict the development of early cycled reentry, potentially culminating in VF, and requires ...

Electrocardiograms of each patient showed right bundle-branch block. In both affected siblings ... siblings died of progressive fibrosis of the cardiac conduction system and cardiomyopathy ...

The CCS generates and propagates electrical impulses critical for the heart's rhythmic contractions ... atrioventricular block, and bundle branch block significantly increase mortality.
