It is hypothesised that the adhesion of electrodes and acceptability of the Electrocardiogram (ECG) trace is comparable between the two groups (marketed and test products) after 30 minutes (the intended period of use) of the electrodes.

Condition Intervention Phase
Healthy Subjects
Device: Marketed electrode
Device: Modified "test" electrode
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Official Title: A Comparative Wear Test of Two Adhesives on the Unilect ™ Biotab Short Term Monitoring Electrode

Further study details as provided by ConvaTec Inc.:

Primary Outcome Measures:
  • Product Performance : Remain in place [ Time Frame: 30 minutes ]
    Ability to remain in place for a duration of 30 minutes (as per intended use)

  • Product Performance: Perform [ Time Frame: 30 minutes ]
    Ability of the electrodes to perform after a duration of 30 minutes of wear (ECG tracing) as per intended use.

Secondary Outcome Measures:
  • Safety: Adverse Events [ Time Frame: 2 days ]
    Safety will be evaluated by the nature and frequency of adverse events, (including condition of the skin under the electrodes using the Skin Irritation Scale (Appendix 4)) and ease of removal

  • Skin Rating [ Time Frame: 2 days ]
    Condition of the skin under the electrodes using the Skin Irritation Scale

Estimated Enrollment: 20
Study Start Date: June 2012
Estimated Study Completion Date: June 2012
Estimated Primary Completion Date: June 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Marketed electrode
The currently marketed electrodes using the current CE marked adhesive
Device: Marketed electrode
12 electrodes will be placed on the subject for an ECG reading to be taken
Active Comparator: Modified hydrogel
Electrodes with the new modified adhesive - the "test" electrodes
Device: Modified "test" electrode
12 electrodes with modified adhesive will be placed on the subject to allow an ECG reading to be taken


Ages Eligible for Study:   Child, Adult, Senior

Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Provide written informed consent
  • Be a healthy volunteer and be over 18 years of age
  • Willing to attend two scheduled visits for application and removal of the device and adverse event review
