Brief Summary:
Medtronic is sponsoring a quality improvement study called Brady MX. It is hypothesized that lack of awareness of treatment and diagnostics pathways result in lower number of referrals to implanters of IPG.

Condition or disease Intervention/treatment
Sinus Node Disfunction Device: IPG

Study Type : Observational [Patient Registry]
Actual Enrollment : 113 participants
Observational Model: Cohort
Time Perspective: Prospective
Target Follow-Up Duration: 6 Months

Intervention Details:
  • Device: IPG
    Patient might require IPG device to be implanted under standard of care

Primary Outcome Measures :
  1. Absolute change in the proportion of subjects diagnosed with SND at pre specific time. [ Time Frame: 6 months ]

Secondary Outcome Measures :
  1. Number of SND subjects receiving a referral for an indicated IPG device after the intervention [ Time Frame: 6 months ]
    The change between subjects referred to an indicated IPG will be measured after the intervention in total number of patients that are referred correctly.
