A woman in her 60s with a broad complex tachycardia. There are two ECG features that suggest an accessory pathway, can you spot them?
In patients with WPW pattern and atrial fibrillation, the presence of an accessory pathway allows for rapid AV conduction, with potential for degeneration into VT and VF

A teenager in atrial fibrillation with a worrying family history. A very unusual looking ECG with Familial Fibrillation... congenital SQTS
Atrial fibrillation is an irregularly irregular tachydysrhythmia characterised by the presence of chaotic fibrillation waves on ECG, rather than p waves, due to disorganised electrical activity in the atria.
Atrial fibrillation (AF) is the most common sustained dysrhythmia and is characterised by disorganised atrial electrical activity and contraction resulting in an "irregularly irregular" ventricular response ("fibrillation waves")
Ashman phenomenon (1947) aberrant ventricular conduction, usually of RBBB morphology, which follows a short RR interval and preceeded by a relatively prolonged RR interval.
