Bezold–Jarisch reflex mediated syncope in pulmonary arterial hypertension: An illustrative case series

Abstract

Abstract We present a novel description of Bezold–Jarisch Reflex (BJR) during cardiopulmonary exercise testing (CPET) in three young female patients with Group 1 pulmonary arterial hypertension (PAH). These three cases presented within 26 months, representing only 0.8% of 11,387 tests on patients with PAH undergoing CPET during this time frame.
