The primary objective of this study is to estimate the proportion of hemodialysis patients experiencing clinically significant cardiac arrhythmias over a 6-month period using continuous cardiac monitoring with an implanted Medtronic Reveal Insertable Cardiac Monitor (ICM) device.

Condition Intervention
End Stage Renal Disease
Device: REVEAL Insertable Cardiac Monitor (ICM)

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Official Title: Monitoring in Dialysis

Primary Outcome Measures:
  • Estimate the proportion of hemodialysis patients who experience clinically significant cardiac arrhythmias using continuous cardiac monitoring over a 6-month period with an implanted Medtronic Reveal ICM device. [ Time Frame: 6 months of dialysis data following Reveal ICM implant ]
    Events defined as clinically significant for the objective include: episodes of ventricular tachycardia (VT) greater than or equal to 130 beats per minute (BPM), episodes of bradycardia indicated by a recorded heart rate less than or equal to 40 BPM, instances of asystole lasting at least three seconds, or any symptomatic event, indicated by patient use of the Reveal ICM Patient Assistant, where review of the stored ECG shows an arrhythmia considered clinically significant in the judgement of the study site cardiologist.

Secondary Outcome Measures:
  • Collect the number of device and procedure related adverse events (AEs). [ Time Frame: 6 months of dialysis data following Reveal ICM implant ]
  • Correlate clinically significant arrhythmias (as defined above) to hemodialysis session parameters and health-related events associated with ESRD. [ Time Frame: 6 months of dialysis data following Reveal ICM implant ]

Enrollment: 81
