Diagnosis Economics Harm/ aetiology Prognosis Therapy Supraventricular Ventricular

Atrial flutter radiofrequency ablation reduced hospitalisation and development of AF compared with medical therapy Level of evidence 1b Expiry Date October 2004 Atrial fibrillation, supraventricular tachycardia propafenone reduced symptomatic arrhythmias Level of evidence 2b Expiry Date November 2004 Cardioversion anticoagulation reduced embolic events. Level of evidence 4 Expiry Date June 2004 Supraventricular tachycardia flecainide prevented symptoms more effectively than verapamil. Level of evidence 1b Expiry Date October 2004 Supraventricular tachycardia paroxysmal: adenosine was as effective as verapamil. Level of evidence 1b- Expiry Date November 2004 Supraventricular tachycardia paroxysmal: adenosine terminated most episodes. Level of evidence 1b Expiry Date November 2004 Supraventricular tachycarda paroxysmal: adenosine was more effective when given through a central venous line. Level of evidence 1b Expiry Date November 2004 Supraventricular tachycardia re-entrant: diltiazem effectively terminated the arrhythmia. Level of evidence 1b Expiry Date October 2004 Syncope carotid sinus massage was safe. Level of evidence 2b Expiry Date October 2004 Tachycardia Valsalva manoeuvre was not clearly better than carotid sinus massage. Level of evidence 1b- Expiry Date August 2004 Tachycardia Sotalol decreased recurrence. Level of evidence 1b Expiry Date August 2004 Tachycardia Sotalol increased conversion to sinus rhythm. Level of evidence 1b Expiry Date October 2004 Tachycardia Flecainide is not clearly different to verapamil. Level of evidence 1b- Expiry Date August 2004 Tachycardia sotalol had no clear difference in rhythm conversion. Level of evidence 1b- Expiry Date October 2004 Tachycardia nadolol increased positive responses Level of evidence 1b Expiry Date August 2004 Tachycardia Sotalol increased termination of arrhythmia. Level of evidence 1b Expiry Date October 2004 Tachycardia flecainide had a dose-response effect. Level of evidence 1b Expiry Date October 2004 Tachycardia diltiazem shows a dose-response effect. Level of evidence 1b Expiry Date October 2004 Tachycardia propafenone can terminate it. Level of evidence 2a Expiry Date October 2004 Tachycardia esmolol was not clearly better than propranolol. Level of evidence 1b- Expiry Date August 2004 Tachycardia Sotalol increased return to normal sinus rhythm. Level of evidence 2b Expiry Date March 2004 Tachycardia Sotalol increased conversion to sinus rhythm. Level of evidence 1b Expiry Date October 2004 Tachycardia delivery of digoxin had no clear effect on conversion to sinus rhythm. Level of evidence 1b Expiry Date October 2004 Tachycardia verapamil had no clear effect on conversion to sinus rhythm. Level of evidence 1b- Expiry Date October 2003
