Lown-Ganong-Levine syndrome is the acceleration of the conduction of the cardiac impulse with a normal QRS complex. In this condition there are:
- short PR intervals and atrial arrhythmias
- no delta waves
This occurs in the presence of a fast-conducting pathway within the atrioventricular node which causes a short PR interval but permits normal ventricular depolarisation.
The patient may give a history of palpitations.
