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 ...

a right bundle branch block is present. 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 ...
