Cardio Flashcards
Shockable rhythms for cardioversion
Ventricular fibrillation
Ventricular tachycardia
PEA and A systole non shockable
Adenosine is used in
Supra ventricular tachycardia
Atrial fibrillation RATE control treatment:
First line: metoprolol ( or verapamil)
Second line: digoxin
Also possible option: DC cardioversion
Hyperkalaemia treatment
Dextrose/ insulin (drives potassium uptake into cells) + calcium gluconate (stabilise cardiac membrane) + resonium (potassium binder)
Atrial fibrillation rhythm control treatment
Verapamil, Sotalol,
Quinine
Flecanide
Causes of AF
Pirates Pulmonary Disease Ischaemia Rheumatic Disease Anaemia/ Atrial myxoma Thyrotoxicosis ETOH Sepsis Chronic AF - HTN, CHF
Four commonest precipitatants of CHF
Ischemia
Infection
Arrhythmia
Anaemia
Fever with new onset murmur:
Infective endocarditis unless proven otherwise
Three commonest pathogens causing IE
Staph Aureus- IVDU and acute
Strep viridans - dental work and subacute
Enterococcus - gastro related
IE empirical treatment
Benpen
Flucloxacillin
Gentamicin
Signs of congestive heart failure
Gallop rhythm
Elevated JVP
Lung crackles -
Peripheral oedema
Chest Pain Red Flag Ddx
PETMAP Pulmonary embolus Esophageal rupture Tamponade Myocardial infarct Aortic aneurysm Pneumothorax
Anacrotic pulse
Slow rising pulse suggesting Aortic stenosis
Loudest on expiration, squatting
Pulsus alterans
Alternating weak and strong pulse - suggesting severe chronic heart failure
Collapsing pulse
Collapsing water hammer pulse suggests aortic regurgitation. Other signs may include a wide pulse pressure, quincke’s nail bed pulsations, de musset’s head bobbing sign.
Regurgitation heard loudest at left sternal heart border
