Trial summary

This study aims to determine the sensitivity and specificity of a Personal Heart Rhythm Monitor in the detection of prolonged paroxysmal atrial fibrillation (defined as lasting more than 12 hours) against pre-existing implantable devices, seen to be the 'gold-standard' for arrhythmia detection.

About this study

Official title: Testing the Accuracy of an Intermittent Personal Heart Rhythm Monitor (PHRM) to Detect Prolonged Paroxysmal Atrial Fibrillation (PAF) Against Implantable Devices.

This study aims to determine the sensitivity and specificity of a Personal Heart Rhythm Monitor in the detection of prolonged paroxysmal atrial fibrillation (defined as lasting more than 12 hours) against pre-existing implantable devices, seen to be the 'gold-standard' for arrhythmia detection.

Read the detailed description

The Investigators aim to recruit 30 volunteers with implantable devices (either conventional pacemakers, with an atrial lead or implantable loop recorders, devices inserted under the skin to monitor the heart rhythm). They will be attending for their routine pacemaker checks in a number of clinics in Surrey.

Potential participants will have documented prolonged paroxysmal atrial fibrillation (PAF, an intermittent irregular heart rhythm which is known to predispose to stroke), lasting at least 12 hours, identified in the last month prior to the pacemaker check.

Willing patients will then be issued with a PHRM (Personal Heart Rhythm Monitor) device to make heart rhythm recordings for 3 months. They will do this twice-daily for 30 seconds for this period. At the end of the 3 month period patients will undergo a final pacing device check. Identification of prolonged PAF using the PHRM device will be compared to the implantable device.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The sensitivity and specificity of detection of prolonged paroxysmal atrial fibrillation (PAF) using a Personal Heart Rhythm Monitor (PHRM), compared to an implantable device.

    Measured (%) as the number of identified episodes of prolonged PAF using the PHRM compared to the gold standard implantable device in all patients over the 3 month period.

    Measured: 18 months

Secondary outcomes (3)
  1. The sensitivity and specificity of detection of all episodes of PAF using a PHRM, compared to an implantable device.

    Measured (%) as the number of identified episodes of all episodes of PAF (lasting at least 30 seconds) using the PHRM compared to the gold standard implantable device in all patients over the 3 month period.

    Measured: 18 months

  2. Participant compliance with twice-daily recordings with the PHRM for a three month period.

    Measured as actual number of recordings made out of 180 requested recordings and expressed as a percentage.

    Measured: 18 months

  3. The concordance of the interpretation of PHRM recordings by a Research Nurse and blinded Cardiologist.

    The agreement in the diagnosis of normal sinus rhythm and PAF using PHRM recordings between a Research Nurse and Cardiologist expressed as a percentage.

    Measured: 18 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Personal Heart Rhythm Monitor in people with Paroxysmal Atrial Fibrillation and Stroke, run by University of Surrey at 2 sites in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 26 Apr 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The sensitivity and specificity of detection of prolonged paroxysmal atrial fibrillation (PAF) using a Personal Heart Rhythm Monitor (PHRM), compared to an implantable device. (time frame: 18 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Apr 2017.
