Aslanger et al identified a specific ECG pattern concerning for acute inferior occlusion MI in patients with concomitant multi-vessel disease, that does not display contiguous ST-segment elevation or fulfil STEMI criteria
Trifascicular block (TFB) refers to the presence of conducting disease in all three fascicles: RBBB, LAFB, LPFB. LITFL ECG Library
Left Bundle Branch Block LBBB - normal direction of septal depolarisation is reversed (becomes right to left), as the impulse spreads
Right Bundle Branch Block (RBBB) activation of the right ventricle is delayed as depolarisation spreads across septum from left ventricle.
Also known as primary sinus tachycardia, inappropriate sinus tachycardia (IST) is a generally benign condition that has a prevalence of ~1% in the general population
Bifascicular block is the combination of RBBB with either LAFB or LPFB. Conduction to the ventricles is via the single remaining fascicle.
Defined as PR interval > 200ms, commonly caused by AV nodal blocking drugs
RPWT is the time from onset of earliest Q wave or R wave to the peak of the R wave in lateral leads
Ventricular fibrillation (VF) is the the most important shockable cardiac arrest rhythm. The heart is no longer an effective pump
Familial arrhythmogenic disease associated with paroxysmal atrial and ventricular fibrillation, syncope and sudden cardiac death
