APART: Prevention and Automatic Therapy of Atrial Arrhythmias in Patients With Paroxysmal Supraventricular Tachycardias

Prevention and Automatic Therapy of Atrial Arrhythmias in Patients With Paroxysmal Supraventricular Tachycardias Who Need Cardiac Pacing

The goal of APART is the assessment of the therapeutic and preventive stimulation algorithms of the Medtronic AT500 and following devices in patients with atrial tachyarrhythmias and an indication for cardiac pacing according to the German guidelines. Medication is controlled throughout the study with a beta-blocker as the only antiarrhythmic drug.

Inclusion Criteria:

• Indication for cardiac pacing according to the German guidelines
• Documented (electrocardiogram; ECG) atrial arrhythmia during the last three months before enrollment
• Willingness to terminate antiarrhythmic drugs until the first recurrence of an atrial arrhythmia
• Sinus rhythm during 24 hours before implant of the device

Exclusion Criteria:

• Ejection fraction below 40%
• Mechanic prosthesis of the tricuspid valve
• Indication to implantable cardioverter defibrillator (ICD)-implantation
• Pregnancy
