Beat-to-beat hemodynamic monitoring during postexertional syncope suggests that a reduction in diastolic filling rate amid inotropic stimulation may trigger the vasovagal reaction, supporting the need for active recovery.
Crisafulli et al. (2000) conducted a case report in Postexertional vasovagal syncope (n=1). Maximal cycle-ergometer test was evaluated on Hemodynamic parameters (HR, SV, CO, SV/DT, PEP/LVET). Beat-to-beat monitoring during postexertional syncope revealed a dramatic reduction in diastolic filling rate preceding the event, supporting its role in triggering vasovagal reactions.
