Unexpected Cardiac Asystole Caused by Vasovagal Reaction During Venipuncture: A Case Report

Clinical Practice and Cases in Emergency Medicine
Introduction: The vasovagal reaction can lead to benign, self-limiting syncope triggered by stimuli such as pain or emotional stress. However, in rare and severe cases it may result in cardiac asystole. Previous episodes of vasovagal reactions could be a

Physical Manoeuvres to Prevent Vasovagal Syncope and Initial Orthostatic Hypotension

Failure of reflex venoconstriction during exercise in patients with vasovagal syncope

, 1996
In this study, we tested two hypotheses. First, we tested the hypothesis that reflex constriction of the venous capacitance beds in patients with vasovagal syncope is impaired during both subhypotensive lower-body negative pressure.
