Primary Outcome Measures:
  • Inappropriate Shock Free Rate [ Time Frame: Three months post-implant ]
    Incidences of ventricular shock therapy up to three months post implant. Rescue shocks are intended for the treatment of cardiac arrhythmias detected in the ventricle at rates greater than 220 bpm, including arrhythmias that originate in the atria if they are conducted at rates greater than 220 bpm as this can be life threatening if persistent. Shocks delivered for other reasons will be considered inappropriate shocks.


Secondary Outcome Measures:
  • Conversion Success Rate up to Three Months Post-implant [ Time Frame: Three months post-implant ]
    For a pacemaker patient who experiences a spontaneous high rate ventricular arrhythmia, the ASSURE device may provide rescue shocks, a faster and more effective response than external methods of rescue. Successful conversion of an episode is defined by conversion to either; sinus rhythm, sinus tachycardia or atrial pacing by one minute post therapy delivery.


Enrollment: 211
Study Start Date: April 2006
Study Completion Date: June 2011
Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: AV Therapy Assessment group
appropriate system performance of the atrial and ventricular tachyarrhythmia therapies in the ASSURE device
Device: AV Therapy Assessment-B301 investigational device
Atrial and ventricular tachyarrhythmia therapy delivered by the B301 investigational device

Detailed Description:
The Guidant ASSURE device is a fully featured pacemaker with additional atrial and ventricular tachyarrhythmia therapy features. The REASSURE AV study is a clinical evaluation to support approval of these features. This clinical study is intended to provide adequate performance data on two atrial tachyarrhythmia management features, namely the ATS and atrial ATP. In addition data will be collected to verify that the ventricular tachyarrhythmia rescue shock feature performs as intended in the clinical setting in combination with other pacemaker functions.
