Trial summary

The purpose of this study is to demonstrate that the use of a continuous ambulatory monitoring device will reduce both the time to effective rate control and the health care expenditures associated with standard methods of rate control monitoring in patients presenting with atrial fibrillation with a rapid heart rate.

About this study

The purpose of this study is to demonstrate that the use of a continuous ambulatory monitoring device will reduce both the time to effective rate control and the health care expenditures associated with standard methods of rate control monitoring in patients presenting with atrial fibrillation with a rapid heart rate.

Read the detailed description

This is an open, randomized controlled trial to compare a standard rate-control strategy with one using the Cardionet device to guide therapy for the management of atrial fibrillation. Patients presenting to an outpatient clinic or to the Emergency Department with atrial fibrillation with a ventricular rate greater than 100 bpm at rest will be enrolled.

Treatment:

Patients will be prescribed either a beta blocker or a calcium channel blocker, or have their baseline dose increased if already taking one of these agents at the discretion of the treating physician. This is consistent with standard outpatient treatment guidelines for rate control in atrial fibrillation.

Randomization:

At the time of enrollment, patients will be randomized to a standard rate control protocol or a rate-control protocol guided by the Cardionet device.

Standard Care (Comparison Group):

Patients randomized to standard care will have a home patient educator install the Cardionet device within 24 hours after enrollment. The Cardionet device will be used to adjudicate the primary endpoint of adequate rate control in the standard care group. The patient's treating physician will be blinded to the reports from the Cardionet device. These patients will have another office visit with the initial referring physician or a staff cardiologist within the first week after enrollment and weekly thereafter. At this time, adequacy of rate control will be assessed by a standard 12-lead electrocardiogram and patient history. Medication will be adjusted per protocol. The patient will be seen on a weekly basis until adequate rate control is thought to have been achieved.

Rate Control using Cardionet (Study Group):

Patients randomized to use of the Cardionet device will have a home patient educator install the device within 24 hours after enrollment. Electrocardiographic summaries will be reviewed by a research physician three times a week and treatment decisions will be made based on a summary of 24-hour rate control. The physician will contact the patient by telephone and make medication adjustments per protocol. Three-times-weekly transmissions and medication adjustments will continue until adequate rate control is achieved over a period of 24 hours.

What is being measured

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

  1. Time to adequate heart rate (HR) control, defined as resting heart rate ≤ 80 bpm and average heart rate over 24 hours < 100 and no recorded HR > 110% of maximum age-adjusted predicted HR.

Secondary outcomes (1)
  1. Total health care costs associated with conventional and Cardionet based monitoring strategy.

Questions about this trial

What is this clinical trial studying?

A study testing Mobile Cardiac Outpatient Telemetry in people with Atrial Fibrillation, run by Beth Israel Deaconess Medical Center at 1 site in United States.

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 6 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 5 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 1 site in United States. 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.

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?

Time to adequate heart rate (HR) control, defined as resting heart rate ≤ 80 bpm and average heart rate over 24 hours < 100 and no recorded HR > 110% of maximum age-adjusted predicted HR.. 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 5 Apr 2017; AzTrials last refreshed its copy on 8 Nov 2026.
