Clinical value of portable 12-lead electrocardiography devices in patients with heart disease: A validation study.

Objective: The present study was conducted to assess the accuracy and reliability of portable 12‑lead electrocardiography (ECG) devices in patients with heart disease.

Materials And Methods: This single-center, prospective, blinded study enrolled 62 patients between September and October 2023 from the Heart Center of a Class III hospital. In sequential tests on each patient, heart rate (HR) and the PR, QT, QTc and QRS intervals of ECG recordings obtained with a portable 12‑lead device (Weheal, CN) were compared with those obtained via conventional 12‑lead ECG.
