Right ventricular pressure, dP/dt, and preejection interval during tilt induced vasovagal syncope.


This study examined the potential utility of monitoring right ventricular dP/dt as a means of detecting imminent vasovagal syncope. To assess this possibility, continuous right ventricular pressure measurements were recorded in nine patients during induction of syncope by head-up tilt testing. Findings indicated that arterial pressure tended to fall prior… (More)
