Syncope and HTN Flashcards
What are the Criteria in the San Francisco Syncope Rule?

SOB
Systolic BO <90mmHg
What is the prodrome for neurally mediated syncope?
Abdominal pain, nausea
Vision changes, dizziness
Slow pulse
What is orthostatic hypotension?
What are the characteristic symptoms?
reduction in SBP >20 or diastolic >10 within 3 min of standing
Dizziness and presyncope with sudden postural changes
What is the prodrome for cardiac syncope?
Often none
chest pain, palpitations
often while supine or with exertion
What is the most important feature in dignosing syncope?
What are some key elements to ascertain?
History
LOC
Hx of CV disease
Clinical features to suggest specific cause?
what are some recommended studies for diagnosing syncope?
Stress test-exertional syncope
TTE-structural heart dz
EPS-suspected arrhythmia
MRI/CT-only specific circumstances
What are some cardiac monitors for evaluating syncope?
Holter-sx that recur within 24-72 hrs
Event-Pt activated, sx recur in 2-6wks
External loop-Continuous activated or auto, sx recur in 2-6wks
Internal-SubQ, 2-3yrs, for infrequent syncope
What kind of syncope pt would you dispo as “observation”
over 50 with h/o cardiac disease
functioning cardiac device
abnormal EKG
Fh of sudden cardiac death
sx do not point to neurally mediated
What kind of syncope patient would be admitted?
major arrhythmia
serious CV condition
noncardiac condition like trauma or severe anemia
How is neurally mediated syncope managed?
reassurance, avoid triggers
expand plasma volume with fluid/salt
physical counterpressure maneuvers of limbs to reduce syncope by 39%
What is the management of orthostatic hypotension?
Remove reversible causes
nonpharm interventions (education)
pharm-midodrine
What is the management for cardiac syncope?
EPS in patients with suspected arrhythmic etiology only
Treat underlying cardiac disorder
What are the main pathological consequences of HTN?
heart maladaptations
brain-CVA, dementia, encephalopathy
Kidney injury
peripheral artery disease
What is normal BP?
What is elevated BP?
What is stage 1 HTN?

What is pregnancy HTN?
<120/80
120-129/<80
130-139/80-89

UA
EKG
According to ASCVD criteria, which patients are automatically placed in the high risk category in regards to HTN?
Patients with DM, CKD, or over 65
Patients with stage 2 HTN are treated with how many HTN agents?
Two ant-HTN agents of different classes
2-4 weeks after initiation of RAAS inhibitors or diuretics, what should be checked?
Electrolytes and renal function
What is the goal BP for HTN management?
<130/80

RAASi
CCBs
thiazide diuretics
What is the anti-HTN of choice in Black patients?
What about for white patients?
CCB or Diuretics in Black patients
ACEi or ARBs in white patients
What drugs should go together for these comorbidities?
DM2 and HTN
CHD or CHF with HTN
BPH and HTN
Afib and HTN
ACEi or ARBs
ACEi or ARBs, B-blockers
a-blockers
CCBs or B blockers
