Neurally Mediated Syncope:
😵Response to Noxious Stimuli, Baroreceptor Activation, Vagal Reflex
🫀Leads to ⬇️HR +/- ⬇️BP
🧠Usually quick reorientation. If prolonged recovery, consider head injury!
🍔Post-Exercise/Postprandial: vascular bed vasodilation

There are many causes/classifications of syncope:
🫀Neurally Mediated (Vasovagal, Carotid Sinus, Situational)
🫀Neurogenic Orthostatic (Meds, Dehydration)
🫀Arrhythmic (VT, LQTS)
🫀Structural Cardiac (HCM, Ischemia)
🫀Dire (PE, Ao Dissection)

An upright systolic blood pressure of 50-60 mmHg at the level of the heart🫀is approximately equal to 30-45 mmHg in the brain 🧠.
This will lead to syncope.
Cerebral hypoperfusion leads to syncope after 6-8 sec.

The strongest determinant of recurrent peripartum cardiomyopathy is an LVEF < 50% before the subsequent pregnancy.
🤰 Residual LVEF < 50% is associated with a higher risk of recurrent HF, worsening of LVEF, mortality, worse fetal outcomes.
#CVBoardPearl #CardioTwitter #CardioOB

Peripartum Cardiomyopathy is defined as:
🤰NEW onset LVEF<45%
🤰± ventricular dilation
🤰NO reversible causes (dx of exclusion)
🤰Occurs towards the end of pregnancy up to the months following delivery (no longer a specific time before/after delivery)
