Clinical Trial: Increasing Atrial Base Rate Pacing to Reduce Atrial Fibrillation

Study Status: Completed
Recruit Status: Completed
Study Type: Interventional

Official Title:

Brief Summary: This study aims to determine whether increasing atrial base rate pacing to achieve at least 75-80% atrial pacing in patients with sick sinus syndrome undergoing the implementation of dual-chamber pacemaker can be useful to prevent or decrease the atrial fibrillation during 6 months follow-up duration.

Detailed Summary:
Sponsor: Urmia University of Medical Sciences

Current Primary Outcome: Atrial high rate/Automatic mode switch episodes [ Time Frame: During 6 Months ]

The number of AHR/AMS episodes recorded by pacemaker


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Stroke [ Time Frame: During 6 months ]
    The development of stroke during follow-up
  • Myocardial infarction [ Time Frame: During 6 months ]
    The development of MI during follow-up confirmed by ischemic chest pain, 12-ECG, or cardiac enzyme elevation
  • Heart failure [ Time Frame: During 6 months ]
    The development or progression of heart failure during follow-up
  • Worsening Functional Class [ Time Frame: During 6 months ]
    The worsening of functional class
  • Death [ Time Frame: During 6 months ]
    Death


Original Secondary Outcome: Same as current
