Written with AI assistance and fact-checked against the sources below. For exam study, not clinical decisions. How notes are made
At a glance
- An accessory pathway (bundle of Kent) bypasses the AV node and pre-excites part of the ventricle.
- Pre-excitation is seen on about 1 to 3 per 1,000 ECGs. Most people never have an arrhythmia.
- Danger: AF conducting down the pathway at very fast rates, which can degenerate to VF.
