What this trial studies

This observational study aims to evaluate the accuracy of electrocardiographic readings obtained from a smartwatch compared to traditional electrocardiograms in patients with cardiovascular diseases. It will analyze the similarities between the readings from both methods and assess the practicality of using smartwatches in clinical cardiology. The study will involve a sample of 110 patients who meet specific cardiovascular criteria, and it will focus on the effectiveness and reliability of smartwatch technology in diagnosing cardiac arrhythmias and conduction disorders.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with various cardiovascular conditions such as hypertension, heart failure, or arrhythmias.

Not a fit: Patients with poor quality electrocardiographic tracings that hinder diagnosis will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance early diagnosis and monitoring of cardiac conditions, leading to improved patient outcomes.

How similar studies have performed: While the use of smartwatches for health monitoring is gaining traction, this specific approach to diagnosing cardiac arrhythmias is relatively novel and has not been extensively tested in prior studies.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Age ≥ 18 years;
* Presence of one or more of the following diagnoses: systemic arterial hypertension, heart failure, valve disease, coronary atherosclerotic disease, myocardial infarction, endocarditis, myocarditis, diabetes, cardiac arrhythmias and patients with cardiac pacemakers or implantable automatic defibrillators.

Exclusion Criteria:

* Patients who have electrocardiographic tracings, whether obtained from the watch or the conventional method, of poor quality that make it impossible or that makes the diagnosis difficult due to the technical aspect of the performance.
* Withdrawal of the consent form at the request of the patient or guardian.
