Acute Medical Presentations — Flashcards

Flashcard 71: Normal QRS duration?

Answer: • 0.8 - 0.12 seconds

Flashcard 72: What does this ECG show?

Answer: Atrial Flutter with variable block

Flashcard 73: 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 74: 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.

Flashcard 75: ACS may present with atypical chest pain in?

Answer: Females, Diabetics, and Elderly patients

Extra: Atypical presentations of Acute Coronary Syndrome (ACS) include dyspnea, fatigue, nausea, or epigastric pain instead of classic retrosternal chest pressure. These are most commonly seen in women, individuals with diabetes mellitus (due to neuropathy), and the elderly.

Flashcard 76: What is the appropriate treatment for Torsades de Pointes?

Answer: • IV magnesium sulfate

Flashcard 77: What MI presents with tall R waves V1-2

Answer: • Posterior MI

Flashcard 78: 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 79: QRS of 0.14 seconds and 130 HR?

Answer: • Broad complex tachycardia

Flashcard 80: Persistent ST elevation following a recent MI, but without ongoing chest pain, is most suggestive of:

Answer: Left Ventricular Aneurysm (Post-MI)

Extra: Persistent ST elevation (>2 weeks post-MI) in the absence of chest pain is most characteristic of a left ventricular aneurysm. This is often associated with a 'squared-off' appearance of the ST segments and Q-waves in the affected leads.
