Validation of 12-lead Smartphone-based spandan ultra 12L electrocardiogram durations and amplitudes analysis as compared to the standard 12-lead electrocardiogram

This study evaluated the accuracy of a smartphone-based 12-lead ECG device (Spandan Ultra 12L) compared to a standard 12-lead ECG system (Philips PageWriter). Conducted on 330 participants in a hospital setting, the analysis found no significant differences between the two devices across ECG intervals, amplitudes, and durations.

Diagnostic agreement of smartphone-based electrocardiogram with coronary angiography in identifying vessel involvement in patients with myocardial infarction

This single-arm, cross-sectional study of 109 MI patients in Dehradun evaluated the diagnostic agreement of Portable ECG (Spandan Pro) and conventional ECG with coronary angiography (CAG) for vessel involvement. The cohort had a mean age of 58 ± 11.96 years and was predominantly male (88%). Portable ECG demonstrated slightly higher sen...
