Cardiology Flashcards
What coronary artery is linked to changes in V1-V4?
Left anterior descending
What coronary artery is linked to changes in II,III and aVF?
Right Coronary
What coronary artery is linked to changes in V1-V6, I, aVL?
Proximal left anterior descending
What coronary artery is linked to changes in I, aVL +/- V5-6?
Left circumflex
What is the management of chronic heart failure?
1) ACEi and BB
2) Aldosterone antagonist ( Spironolactone) + SGLT-2 inhibitor
What does LBBB look like on an ECG?
W in V1 and M in V6
What are some causes of LBBB?
MI
Hypertension
Aortic Stenosis
cardiomyopathy
What is first line medication for PE?
DOAC ( e.g. apixaban) when first suspected, then continued if confirmed
Unprovoked - 6m
Provoked - 3m
What is the first line management of Acute Pericarditis?
Ibuprofen + Colchicine
When should a patient be admitted for acute pericarditis?
temp >38
elevated troponin
What are some causes of acute pericarditis?
- viral infection ( Coxsackie)
- TB
- Uraemia
- Post MI early –> fibrinous pericarditis
- Post MI late –> Dressler’s Syndrome
- Radiotherapy
- connective tissue
If patient cannot tolerate ACEi what do you switch their medication to?
ARB ( e.g Candesartan)
What is Brugada syndrome?
Inherited Cardiovascular disease
Autosomal dominant inheritance
Mutation that codes Myocardium Sodium Ion Channel protein
What hypertension management drug should you avoid using when patient has gout?
thiazide-like diuretics
What is the first line mediation used in bradycardia?
Atropine ( 5oomcg IV)
What anti-coaculant to use with someone with a mechanical valve?
Warfarin
What rhythms are shockable?
VT/VF
What rhythms are not shockable?
Asystole / Pulseless electrical activity
How does shocking the patient differ when they are being monitored?
do 3 quick shots
What DOAC is preferred in someone with a mechanical valve?
Warfarin
First line rate control in AF
Beta blocker
Posterior on MI
Tall R waves in V1-V2
How to notice Cardiac tamponade on an ECG?
Electrical alterans
QRS complexes different heights
due to swinging of heart
Presentation of Cardiac Tamponade
Becks triad : Low BP, Elevated JVP , muffled heart sounds
dyspnoea, tachycardia
pulsus paradoxus
absent Y wave ( Y wave describes ventricular filling, fluid build up means the heart unable to relax and fill)
Management of cardiac tamponade
urgent pericardiocentesis
How do vasopressors work?
vasoconstriction - act on V1 receptors
increase SVR
increase MAP
What are the different types of aortic dissection? (Stanford classification)
Type A : Ascending aorta
Type B : descending aorta
How to manage aortic dissections?
Type A : IV labetalol + Surgery
Type B : IV labetalol
Patient on ACEi + signs of CKD + K>=6.
What do you do?
swap ACE
Description of Torsades de Pointes on an ECG
polymorphic ventricular tachycardia
prolonged QT intervals
How to manage torsades de pointes?
IV magnesium sulphate
What drugs cause prolonged QT interval?
Anti-arrhytmics
anti - B iotics –> macrolides and fluoroquinolones
anti - psyChotics & Cholorquine
anti -Depressants & thiazide- diruetics –> TCAs
anti -Emetics
anti-Fungals
