Brugada syndrome
- The Brugada syndrome manifests as ST elevation with a right bundle branch pattern in the right precordial leads. Is treated with implantation of an AICD.
STEMI and Arrhythmias
Implantable Cardiac Defibrillator
- Should not be implanted within 40 days of STEMI
- A patient should wear a defibrillator vest while awaiting AICD implantation
- Amiodarone improves CV survival but not all cause survival in patients with an LVEF of <40%
Atrial Fibrillation
Rate Control vs Rhythm Control
- Rhythm control offers no benefit over rate control in survival
- Rate control is very important in preventing the tachycardia cardiomyopathy syndrome
Radiofrequency Ablation
- A complication of radio frequency ablation is left atrial tachycardia or flutter. This complication may itself require treatment.
- Anticoagulation should be continued after radiofrequency ablation.
- In patients who have a rapid ventricular response rate in atrial fibrillation and who develop a tachycardia induced cardiomyopathy, AV junctional ablation can be undertaken with permanent pacemaker placement.
