Synchope, Weakness, Death Remediation

Yes

What is the difference between collapse and weakness

collapse is a sudden loss of postural tone (not necessarily consciousness), weakness is a state of lacking strength

define presyncope

partial to near loss of consciousness often associated with mental dullness, transient wobbliness or weakness

define syncope

TLOC: subset of collapse involving loss of consciousness and collapse

General cause of syncope

transient local, global cerebral hypoxia and hypertension

define cardiogenic syncope

intermittent, profound, abrupt hypotension

causes of cardiogenic synchope

marked reduction of cerebral blood flow, decreased O2 to RAS, excitement/exertion (increased O2 demand), arrythmias

how does structural cardiac disease cause syncope

obstruction of outflow leading to low cardiac output

define neurocardiogenic syncope

sudden autonomic nerve system fail

triggers of neurocardiogenic syncope

exited, cough, GI illness, vasodilation, bradycardia

causes of non syncopal collapse

neurogenic (seizure), respiratory (URO, pulm hypertense), narcolepsy, exercise-induced, neuromuscular disease, metabolic disease, OD of cardiovascularly active drugs.

what is tussive syncope

coughing increases intrathoracic pressure and decreases venous return triggering reflex bradycardia and vasodilation

Define syncope

breif, low blood flow to the brain, rapid recovery

define seizure

longer, abnormal electrical activity, convulsion, post-ictal stage

what step of diagnostics is essential for differentiating syncope from seizure

history

diagnostic plan for evaluating syncope

hx, phys exam, electrocardiogram, echocardiogram, cbc/chem/ua, thoracic radiographs, maybe holter monitoring

most common progression of sudden cardiac death in dogs

v tac to v fib

differentials for sudden cardiac death in dogs

DCM, arythmogenic RV cardiomyopathy, subaortic stenosis, pulmonic stenosis, chronic degenerative valve disease

Differentials for sudden cardiac death in cats

HCM, restrictive cardiomyopathy, unclassified cardiomyopathy
