Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)

Primary Outcome Measures:
  • Procedure-related Complications Rate Requiring Resolution by Surgical Intervention [ Time Frame: From Implant to 90 days post-implant procedure ]
    This objective estimates the proportion of patients having procedure-related complication requiring resolution by surgical intervention at 90 days post-implant procedure using Kaplan-Meier method.

Secondary Outcome Measures:
  • Number of Participants Having Procedure-related Adverse Events [ Time Frame: From Implant to 90 days post-implant procedure ]
    Report number of participants having procedure-related adverse events that meet the primary endpoint (requiring surgical intervention), and number of participants having other procedure-related adverse events (not requiring surgical intervention).

  • Surgical Staff Utilized for Reveal In-office Implants [ Time Frame: At implant ]
    Observational analysis of surgical staff present at the Reveal Implants

  • Techniques and Procedures Utilized During Reveal In-office Implants [ Time Frame: At implant ]
    Observational data collection as to the technics and procedures utilized during all implants including (but not limited to): device orientation, suturing, wound closure, instrument and material use, and time.

  • Physician Satisfaction With Reveal In-office Implants [ Time Frame: At implant ]
    Observational survey of physicians satisfaction post implant At implant

  • R-wave Amplitude Measurement [ Time Frame: Implant procedure and 30 days post-implant procedure ]
    Average R-wave amplitude at implant and 30-days post procedure

Enrollment: 66
Study Start Date: August 2010
Study Completion Date: May 2011
Primary Completion Date: May 2011 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: Reveal® DX or Reveal® XT Insertable Cardiac Monitor
    Reveal® DX and Reveal® XT Insertable Cardiac Monitors are implantable patient-activated and automatically-activated monitoring systems that record subcutaneous ECG.
