Cardiology Flashcards
What are 10 findings to look for on ECG in a patient with syncope?
- Tachydysrhythmias
- Bradydysrhythmias
- Long QT
- Short QT
- ST changes in MI
- PE - sinus tachycardia, RBBB, RVH, S1Q3T3
- Brugada syndrome
- ARVD - epsilon wave
- HOCM - dagger Q waves in lateral leads, LVH, LV strain
- WPW/re-entry pathways
What is Wellen’s syndrome?
Wellens’ syndrome is a pattern of deeply inverted or biphasic T waves in V2-3, which is highly specific for a critical stenosis of the left anterior descending artery
What are the diagnostic criteria for Wellen’s syndrome (Rhinehart 2002)
Deeply-inverted or biphasic T waves in V2-3 (may extend to V1-6)
Isoelectric or minimally-elevated ST segment (< 1mm)
No precordial Q waves
Preserved precordial R wave progression
Recent history of angina
ECG pattern present in pain-free state
Normal or slightly elevated serum cardiac markers
What is the DDx of Wellen’s syndrome changes on ECG
Pulmonary embolism Right bundle branch block Right ventricular hypertrophy Left ventricular hypertrophy Hypertrophic cardiomyopathy Raised intracranial pressure Normal paediatric ECG Persistent juvenile T wave pattern Brugada syndrome Hypokalaemia
What is the Type A Wellen’s pattern
- Biphasic precordial T waves with terminal negativity, most prominent in V2-3.
- Minor precordial ST elevation.
- Preserved R wave progression (R wave in V3 > 3mm)
What is the Type B Wellen’s pattern
Biphasic T waves in V2-3
What is an Impella?
Percutaneous left ventricular assist device placed from the femoral artery, tip sits in the LV
Temporary
Works to create forward flow out the LV to the aorta
Only increased cardiac output by 0.25
What are 3 complications of pericarditis
- heart failure
- pericardial effusion leading to tamponade
- dysrhythmias
