What this trial studies
This observational study aims to evaluate the effectiveness of smartwatch technology in detecting paroxysmal arrhythmias compared to traditional Holter monitoring. Participants aged 18 to 80 who are referred for outpatient Holter exams due to symptoms like palpitations, dizziness, or pre-syncope will be recruited. The study seeks to address the limitations of Holter monitoring, which often has a low diagnostic yield due to the sporadic nature of arrhythmias. By utilizing smartwatches, the study hopes to improve the correlation between symptoms and arrhythmia detection.
Who should consider this trial
Good fit: Ideal candidates are adults aged 18 to 80 referred for Holter monitoring due to symptoms like palpitations or dizziness.
Not a fit: Patients with a prior ECG diagnosis explaining their symptoms or those whose primary symptom is syncope may not benefit from this study.
Why it matters
Potential benefit: If successful, this approach could lead to more accurate and timely detection of arrhythmias, improving patient outcomes.
How similar studies have performed: While traditional Holter monitoring has been widely used, the use of smartwatches for arrhythmia detection is a relatively novel approach with limited prior studies.
