Cardio Flashcards
(23 cards)
When would adenosine be contraindicated for treatment of SVT?
In asthmatic patients: first line then would be verapamil
What drug should be given prior to fibrinolysis for a STEMI?
Fondaparinoux (anti thrombin drug to prevent the clot getting better)
Fibrinolysis used when PCI cannot be done within 2hrs
Give in addition to MONA tx for all ACS
What is the management of supraventricular tachycardia?
Narrow complete tachycardia (QRS<120ms)
If unstable: up to 3 shocks
If stable:
1st: Carotid sinus massage/ vagal manoeuvre
2nd: Adenosine IV (6->12->18mg)
How can atrial fibrillation be managed?
<48hrs of onset: cardioversion
>48hrs: DOAC (to avoid atrial thrombus formation), and in 3 weeks cardiovert
Rate control with beta blockers
Digoxin or amiodarone if evidence of heart failure
How can a broad complex tachycardia be managed?
If unstable: up to 3 shocks
If stable: Loading dose of amiodarone followed by 24hr infusion
What is the management of torsades de pointes?
IV Mg
What ECG changes can be seen in hyperkalaemia?
Tented T waves
Loss of P waves
Widened QRS
Which heart valve is most commonly affected in infective endocarditis of an IVDU?
Tricuspid valve
U waves on ECG indicate what?
HypoK
HypoCa
Hypothermia
What ECG changes are seen in hypokalaemia?
U waves
Flattened T waves
Long PR & QT
“U have not Pot and no Tea with a long QR and QT”
What is the immediate treatment of bradycardia with signs of shock?
500microgram atropine IV (up to maximum 3mg)
What secondary prevention medication should be started following acute coronary syndrome?
DAPT (aspirin lifelong + another anti platelet 1yr)
Statin
ACEi
Beta blocker
J waves on an ECG are pathognomic for what?
Hypothermia
ST elevation in leads II, III & aVF indicates MI in which territory?
Inferior (right coronary artery)
Delta wave on ECG is associated with which condition?
Wolff Parkinson White syndrome
(Pre-excitation of the ventricles due to an accessory pathway which bypassses the AV node)
Delta stroke is slurred upstroke of the QRS
GRACE score higher than 3% indicates what?
Should undergo PCI within 72 hours if NSTEMI
What is the most common cause of mitral valve stenosis?
Rheumatic fever
Mitral stenosis presents with which type of murmur?
Diastolic murmur
What ECG changes are seen in pericarditis?
PR depression (most specific)
ST elevation “saddle shaped”
(Widespread)
What is the presentation of pericarditis?
Classical chest pain relieved by sitting forwards
Flu symptoms
Dyspnoea
Cough (non productive)
Pericardial friction rub
What is the treatment for pericarditis?
Treat underlying causes
1st line is NSAIDs + colchicine
What is the best management for NSTEMI with a GRACE score >3%?
Aspirin 300mg and then PCI within 72 hours
(Whereas we aim for 2 hours for a STEMI)
What is the ALS algorithm to manage bradycardia?
If no adverse signs: observe
If adverse signs (shock/ syncope/ HF/ MI) or risk of a systole:
1st line is atropine 500mcg IV, can be repeated up to max of 3mg
If unsuccessful other treatments include adrenaline/ isoprenaline/ transcutaneous pacing
