Arrhythmias with pics Flashcards
what does this ECG show?
-asystole
how to treat asystole?
- non shockable rhythm
- 1 mg adrenaline every 3 to 5 mins
what does this ECG show?
-atrial flutter
how does atrial flutter present on ECG?
- atrial rate>300bpm
- ventricular rate >150bpm
- regular saw tooth wave
treatment for atrial flutter?
FOR RHYTHM CONTROL:
- DCCV
- ablation
FOR RATE CONTROL:
1st line BB/CBB
2nd line digoxin
3rd line amiodarone
anticoagulants
how does atrial fibrillation present on ECG?
- irregularly irregular with no P waves
- atrial rate >300bpm
- ventricular rate varies
what does this ECG show?
atrial fibrillation
treatment for atrial fibrillation?
Same treatment as atrial flutter
FOR RHYTHM CONTROL
- DCCV
- ablation
FOR RATE CONTROL
1st line BB/CCB
2nd line digoxin
3rd line amiodarone
anticoagulants
what does this ECG show?
pericarditis
how does pericarditis present on an ECG?
- saddle shaped ST segment
- PR depression
How does Brugada syndome present on ECG?
ST elevation anf RBBB in V1-3
May have AF too
How does congenital long QT syndrome present on an ECG?
- QT prolongation (>0.44s in males and >0.45s in females)
- Torsades de Pointes (polymorphic VT)
What does this ECG show?
Torsades de Pointes (ventricular tachycardia)
How to treat congenital long QT syndrome?
- BB
- avoid QT prolonging drugs and triggers
How does first degree heart block present on an ECG?
- PR interval is prolonged (>0.2s)
- regular and no missed beats
How does Mobitz Type 1 present on an ECG?
-Progressively lengthening PR interval until a beat (QRS complex) is dropped
How does Mobitz Type 2 present?
-PR interval is constant but the P wave is often not followed by QRS complex
