Qualitative Analysis of Photoplethysmography Waveforms for the Detection

Status Completed

Clinical Trial Summary

Single-lead electrocardiography (ECG) technologies and photoplethysmography (PPG) deriving smartphone apps are gaining interest in the heart rhythm detection space since these apps have the potential to capture and assess heart rhythms. Proprietary arrhythmia detection algorithms are proven to be reliable and accurate. However, insights into the readability of PPG waveforms by human reviewers remain limited. To the investigators' knowledge, there are no publications available regarding the readability of PPG waveforms by human reviewers. The objective of the study was to assess the readability of PPG and single-lead ECG analysis by medical professionals, with respect to the gold-standard 12-lead ECG diagnosis, and investigate whether additional information positively impacts PPG analysis.

Clinical Trial Description

During the study, the readability of PPG and single-lead ECG waveform analysis will be investigated. The objective of the study is to determine the readability of PPG and single-lead ECG measurements, with respect to the gold-standard 12-lead ECG, and investigate whether additional information positively impacts the readability of PPG. Medical professionals (cardiologists and cardiology residents), blinded for the patients' characteristics and history, are instructed to separately analyse the following signals, obtained from 30 patients. - 30 outputs with PPG waveforms - 30 outputs with PPG waveforms with tachogram and Poincaré - 30 outputs with PPG waveforms with tachogram, Poincaré, and algorithm interpretation - 30 outputs with single-lead ECG waveforms - 30 outputs with 12-lead ECG waveforms Participants report the results of the qualitative analysis via a digital questionnaire with multiple-choice questions. Medical professionals classify each rhythm trace as regular rhythm, one or more ectopic/missed heartbeats, atrial flutter, atrial fibrillation, unreadable, or other. The tachogram, Poincaré, and the algorithm interpretation are subsequently added to investigate whether the additional information improves the readability of PPG. Based on the provided answers, the study team will determine the readability of PPG and single-lead ECG analysis interpretation, with respect to the gold-standard 12-lead ECG diagnosis. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
