CHADSVASc Score

HASBLED Score

Tx for undifferentiated SVT
IV Adenosine
Slows the HR to see the underlying cause
Brings heart back to sinus rhythm
Warn patient it’ll feel like they are about to die
Causes of AF
PIRATES
- Pulmonary embolism
- Ischaemia (myocardial)
-
Respiratory disease
- Pneumonia
- Lung cancer
- Alcohol or atrial enlargement or myxoma
- Thyrotoxicosis
- Ethanol
- Sepsis / Sleep apnoea
+ Valvular heart disease (esp Mitral)
ECG signs of AF
Absent P waves
Fibrillatory waves
Irregularly irregular rhythm

Tx of AF
Onset < 48 hours
- If unstable –> DC cardioversion
- If stable
- Rate control
- (1) Beta blockers or CCB
- (2) Digoxin
- (3) Amiodarone
- Anticoagulation
- LMWH
- Rhythm control
- TOE + Cardioversion (DC or chemical)
- Flecainide or Amiodarone or Propafenone
- TOE + Cardioversion (DC or chemical)
- Rate control
Onset > 48 hours
- Rate control (as above)
- Anticoagulation
- Heparin + Warfarin (INR 2-3 for 3-4 weeks)
- After 3-4 weeks –> Rhythm control ==> Cardioversion (DC or chemical)
If paroxysmal –> Pill in pocket (Flecainide PRN)
If refractory to cardioversion
- Rate control + Anticoagulation
- Catheter radiofrequency ablation
ECG signs of Atrial flutter
Narrow complex tachycardia
Fixed AV block (150bpm, 100bpm, 75bpm) or Variable
Saw-tooth pattern (flutter waves)

Tx of Atrial Flutter
If diagnostic uncertainty –> Carotid massage or IV Adenosine
Treat underlying cause
Rate control (B blockers, CCB, Amiodarone)
Anticoagulation
Rhythm control (TOE + Cardioversion)
Tx of WPW
If unstable –> Cardioversion
If stable
- If tachycardia
- Carotid sinus massage + Valsalva manoeuvre
- IV Adenosine
- DC Cardioversion
- If symptomatic –> Catheter ablation of accessory pathway
ECG features of VT
Broad QRS + tachycardia
Capture beats (pathognomonic)
Fusion beats

Tx of VT
Unstable
- (1) DC Cardioversion
- (2) Correct electrolytes
- (3) Amiodarone
Stable
- (1) Correct electrolytes
- (2) Amiodarone
- If refractory –> DC Cardioversion
If Torsades de Points –> Magnesium sulphate
Tx of sinus bradycardia
Atropine
Systolic vs Diastolic HF

L vs R heart failure vs CCF

New York Heart Association (NYHA) Classification
NYHA 1 : disease present, no limitation
NYHA 2 : slight limitation, improves with rest
NYHA 3 : marked limitation on exertion, improves with rest
NYHA 4 : SOB at rest
Ix for heart failiure
Screening –> BNP (sensitive but not specific)
If high BNP or abnormal ECG or Hx of MI –> Doppler Echo (diagnostic)
Tx for acute pulmonary oedema
FOGDC
IV Furosemide
+/- Oxygen
+/- IV Diamorphine
+/- IV GTN
+/- CPAP
+/- Intubation + Ventilation
Tx of heart failure
ALL HF
- Loop diuretics (symptomatic)
- +/- Anti-platelet
- +/- Statin
If EF < 55% (systolic heart failure) ==> ABCD HI DICD
- (1) ABCD
- ACE inhibitor + B blocker (only start one at a time)
- If EF < 35% –> +/- Spironolactone
- (2) +/- Hydralazine + Isosorbide dinitrate combination
- (3) If Heart failure + AF –> +/- Digoxin
- (4) If EF < 35% –> +/- ICD or CRT (if LBBB)
- (5) Heart transplant
Recurrent chest infections
Ejection systolic murmur (LUSE)
Fixed, widely split S2
Diagnosis?

Types of heart block
1st degree: fixed prolonged PR
2nd degree (Mobitz 1): progressively prolonged PR , then drop beats
2nd degree (Mobitz 2): fixed PR with drop beats
3rd degree: P-QRS dissociation
Tx for heart block
1st degree and 2nd degree (Type 1)
- If asymptomatic –> monitoring
- If symptomatic –> Elective pacemaker
2nd degree (Type 2) and 3rd degree
