Short VA intervals during tachycardia may exclude accessory AV pathways in PSVT; leaves open prospective validation before diagnostic use.
Do ventriculoatrial interval measurements during tachycardia help exclude the participation of an accessory AV pathway in patients with paroxysmal supraventricular tachycardia?
Measurement of V-A intervals during tachycardia provides a simple screening test to exclude the participation of an accessory AV pathway in paroxysmal supraventricular tachycardia.
