Clinical presentation of Beta blocker overdose

Answer 7

bradycardia and hypotension leading to cardiogenic shock

Question 8

Aortic regurgitation murmur

Answer 8

Early diastolic murmur

Question 9

Vasovagal syncope pathophysiology

Answer 9

Response to from increased parasympathetic activity leading to bradycardia and asystole due to sinus arrest

Question 10

Holosystolic murmur that increases in intensity with inspiration

Answer 10

Tricuspid regurgitation

Question 11

What are the most important factors improving patient survival in cardiac arrest

Answer 11

1. Prompt effective resuscitation with adequate bystander cardio-pulm resuscitation
2. Promt rhythm analysis and defibrillation in a shockable rhythm (eg. V-fib)

SA nodal exit block (dropped P waves)

Question 14

Clinical features of sick sinus syndrome

Answer 14

Elderly patients
Bradycardia (fatigue, dyspnea, syncope, dizziness)
bradycardia-tachycardia syndrome (A-fib, palpitations)

Question 15

Treatment of sick sinus syndrome

Answer 15

1. Pacemaker

2. +/- rate control meds eg. BB (if tachyarrhythmias)

Answer 16

TEE (Preferred in patients with renal insufficiency)
CT Angio (preferred study in hemodynamically stable pts)
MRA

Question 17

What is the next best step in a Asx patient with a diastolic murmur

Question 20

Initial evaluation of coarctation of the aorta

Answer 20
