Cor Pulmonale is ___ heart failure and presents with __
Right sided heart failure
Shortness of breath
What is a common cause of stroke?
Atrial Fibrillation
What would infective endocarditis present with?
Fever New murmur Janeway lesion Osler's nodes Splinter haemorrhages
How does Left Bundle Branch Block present?
Usually asymptomatic
ECG: WiLLiaM (V1, V6)
How does Right Bundle Branch Block present?
ECG: MaRRoW (V1, V6)
Heart failure classic triad
SOB, fatigue, ankle oedema.
Management of Acute Heart Failure
IV Furosemide + Diamorphine + Antihypertensive (GT, diuretic) or Antihypotensive (vasocative DA)
Management of Chronic Heart Failure
ACEi - Ramipril/ ARB - Valsartan + BB + Diuretic - Furosemide
2L Hydralazine/ nitrate/ Digoxin (with AF)
A high BNP level indicates…
Congestive heart failure
How is hypertension classified?
1) >135/85 ABPM
2) >150/95 ABPM
3) >180 S or >110 D
Malignant = >180/120 + end-organ damage
How is hypertension managed
ACEi/ ARB or CCB - Nifedipine (if >55/ Afro-Carib)
ACEi +/- CCB +/- Thiazide-like diuretic - Indapamide/ Spironolactone if K<4.5
How is pregnancy-induced HTN managed?
IV Magnesium Sulphate + Labetalol/ Hydralazine/ Methyldopa
What is Sodium Nitroprusside used for?
Lowering vv high BP
- encephalopathy
- Aortic dissection
- Pulmonary oedema
What is Labetalol used for?
= a BB - 1L for lowering BP in pregnancy
Cannon A-waves, HR <40bom, syncope indicates…
AV Block
What is seen on the ECG of a first-degree AV Block?
Prolonged PR interval >0.2s
ECG shows a PR interval progressively lengthening until P-wave is not conducted.
What SnS will this pt present with?
= Mobitz I (Wenckebach) 2nd degree AV block
Light head, dizzy, syncope
ECG shows a constant PR interval, with a dropped QRS.
What SnS will this pt present with?
= Mobitz II 2nd Degree AB block
SOB, postural hypotension, angina.
Requires permanent pacemaker.
Why is Mobitz II irreversible?
Failure of conduction through His-purkinje system, which is resistant to AV blocking agents
ECG shows P-waves completely independent of QRS.
How is this pt treated?
= 3rd Degree heart block
IV atropine
Permanent pacemaker
Narrow QRS IN BoH. (QRS < 0.12)
Broad QRS BELOW BoH. (QRS >0.12s)
ECG shows saw-tooth F waves in II, III, aVF. They show heart and lung pathologies.
How is this pt treated?
= Atrial Flutter
LMW Heparin THEN electrical cardioversion
Catheter ablation, IV amiodarone, BB
ECG shows irregular irregular rhythm at 400bpm and no p-waves.
How is this pt treated?
= Atrial Fibrillation
Cardioversion: DC Shock + LMW heparin + antiarrhythmic
VR control - block AVN!
- CCB, BB, digoxin, amiodarone
CHA2DS2-VASc Score
