Acute Medical Presentations Flashcard Deck - 10 Cards
Flashcard 61: AF can degenerate rapidly to VF in Wolf-Parkinsons White Syndrome because
The accessory pathway conducts the chaotic atrial activity during AF which bombards the ventricles
Wheras usually the AV node acts as a _____ slowing conduction from the atria to ventricles
This rapid ventricular activation can degenerate into Ventricular Fibrillation (VF)
Answer: physiological gatekeeper
Flashcard 62: Management for Broad-complex tachycardia?
Answer: • If unstable (shock, syncope, MI): Synchronized DC cardioversion\n• If stable: IV Amiodarone (300mg over 20-60 mins)
Flashcard 63: What management can Complete Heart Block warrant?
Answer:
• Transvenous pacing -> risk factor for asystole
*When an emergency flexible pacing wire is placed through the [Internal Jugular/Subclavian Vein] to the right ventricle to correct life-threatening bradycardias
Flashcard 64: Normal QRS duration?
Answer:
• 0.8 - 0.12 seconds
Flashcard 65: What is this?
Answer:
• Wellen's syndrome
*high-grade stenosis in the LAD
*Pt pain may have resolved at the time, and trop = normal/minimially elevated
**Biphasic or deep T wave inversion in Leads V2-3
Minimal ST Elevation
• no Q waves
Flashcard 66: What are the ECG findings in hypokalaemia?
Answer: U have no Pot (K+) and no T, but a long PR and a long QT
(small or absent T waves)
- U waves
- Small or absent T waves
- Long PR
- ST Depression
- Long QT
Flashcard 67: What MI presents with tall R waves V1-2
Answer:
• Posterior MI
Flashcard 68: What is contraindicated in VT?
Answer:
• Verapamil
Flashcard 69: What is the appropriate treatment for Torsades de Pointes?
Answer:
• IV magnesium sulfate
Flashcard 70: Management of a peri-arrest tachycardia with any of the following adverse signs: shock (hypotension, confusion, cold extremities), syncope, MI, heart failure?
Answer: • Synchronised DC shocks
Up to 3 shocks can be given; if unsuccessful, expert help should be sought.
