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.
