About this study

Official title: Assessment of the Clinical Efficacy of the Heart Spectrum Blood Pressure Monitor for Diagnosis of Atrial Fibrillation: An Unblinded Clinical Trial

Question: Is 12-lead electrocardiography (ECG) the most accurate and convenient diagnostic method for atrial fibrillation (AF)? Findings: The Heart Spectrum Blood Pressure Monitor can be used at home, and is capable of determining the occurrence of AF. Three measurement methods were used in this study. The sensitivity, specificity, PPV, and NPV of the methods used are between 90% and 100%, and the Heart Spectrum Blood Pressure Monitor can be effectively applied to AF detection.

Meaning: The Heart Spectrum Blood Pressure Monitor can be used at home and can replace the need for an in-office ECG, thereby accomplishing meaningful telecare.

Read the detailed description

Importance: Atrial fibrillation (AF) is the most common arrhythmia. The most common diagnostic method, 12-lead ECG, can record episodes of arrhythmia from which the type and severity can be determined. The Heart Spectrum Blood Pressure Monitor (P2, OSTAR Meditech Corp.) is used to measure cardiovascular pressure change, with fast Fourier transform (FFT) analysis, to obtain the heart rate frequency variability and accurate blood pressure data.

Objective: To compare the diagnostic efficacy of the Heart Spectrum Blood Pressure Monitor with a 12-lead ECG in patients with AF. Three measurement methods were used in this study: blood pressure, mean arterial pressure (MAP) which is calculated from individual blood pressure as constant pressure, and a constant pressure 60 mmHg, in order to analyze the heart index and compare it with simultaneous 12-lead ECG.

Design: The physician used a 12-lead ECG and the Heart Spectrum Blood Pressure Monitor simultaneously. The Heart Spectrum Blood Pressure Monitor used an FFT analysis for the diagnosis of AF; the findings were compared with the readings from the 12-lead ECG.

Setting: This unblinded clinical trial was conducted at the Emergency Room of Taipei Medical University Hospital.

Participants: Twenty-nine subjects with AF and 33 without AF, aged 25 to 97 years (mean: 63.5 years), were included.

Intervention(s) for clinical trials Subjects who had been exposed to high frequency surgical equipment during testing, those with cardiac pacemakers or implantable defibrillators, and pregnant women were excluded.

What is being measured

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

  1. The Heart Spectrum Blood Pressure Monitor used an FFT analysis for the diagnosis of AF; the findings were compared with the readings from the 12-lead ECG.

    In the emergency room, when medical staff found patients with AF, they informed the research physicians to study the case. The Heart Spectrum Blood Pressure Monitor was compared with 12-lead ECG (ELI 250) after written informed consent was obtained from the patient. The results were interpreted by the emergency physician. Finally, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were analyzed to evaluate the clinical efficacy.

    Measured: monitoring for about 60 seconds per test

Questions about this trial

What is this clinical trial studying?

A study testing Heart Spectrum Blood Pressure Monitor in people with Atrial Fibrillation, run by Ostar Meditech Corp.

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 1 inclusion and 1 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: finished, as of the sponsor's last update on 29 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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 Heart Spectrum Blood Pressure Monitor used an FFT analysis for the diagnosis of AF; the findings were compared with the readings from the 12-lead ECG. (time frame: monitoring for about 60 seconds per test). 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 29 Mar 2017.
