Evidence Based Medicine on Tachydysrhythmias with Drs. Ludmer and Miller

• SVT is an umbrella term that includes AVNRT, atrial fibrillation and flutter, and polymorphic multifocal atrial tachycardia (MAT)
• AVNRT (AV Node Re-entrant Tachycardia) is the correct term for what is commonly diagnosed as SVT, 
• MAT usually occurs in critically ill elderly patients with respiratory failure and is a poor prognostic sign, associated with 60% in hospital mortality. Treatment is to treat the causative pathology.
• REVERT Trial: Modified valsalva vs standard valsalva performed in 10 EDs with 428 patients in England. Findings included a 17% conversion with standard methods and 43% with the modified valsalva.
