Key result
The Spandan smartphone 12-lead ECG demonstrated 100% sensitivity and 81.4% specificity for detecting STEMI compared to a cardiologist's diagnosis, whereas the standard 12-lead ECG showed 91.8% sensitivity.
Why the study?
Rapid STEMI diagnosis leads to optimal clinical outcomes, and this study aimed to evaluate variation in STEMI diagnosis detected by a novel smartphone-based 12-lead ECG compared to the gold standard.
Does a smartphone-based 12-lead ECG accurately detect STEMI compared to standard 12-lead ECG and cardiologist interpretation in patients with chest pain or shortness of breath?

Does a smartphone-based 12-lead ECG accurately detect STEMI compared to standard 12-lead ECG and cardiologist interpretation in patients with chest pain or shortness of breath?
Absolute Event Rate: 100% vs 91.8%
A smartphone-based 12-lead ECG showed potential for evaluating STEMI, though it detected fewer STEMIs (7.1%) compared to standard 12-lead ECG (14.3%) and cardiologist interpretation (15.4%).
May support smartphone ECG for rapid STEMI detection; hypothesis-generating and requires prospective validation before adoption.
Background: In patients experiencing an ST-elevation myocardial infarction (STEMI), rapid diagnosis leads to optimal clinical outcomes. Recent technology has provided access to a reliable means of obtaining an ECG reading through a smartphone application (app) that works with an attachment providing all 12-leads of a standard ECG system. We developed a 12-lead smartphone-based electrocardiogram (ECG) called “Spandan”, and an application to accurately assess the presence of STEMI in patients presenting with chest pain. Objectives of study was to perform clinical observation studies on the patients screened for STEMIs and evaluate the variation in the diagnosis of STEMIs detected in both 12-lead gold standard and Spandan 12 lead ECG. Methods: This single-center study was carried out at Shri Mahant Indresh hospital (SMIH), Dehradun, Uttarakhand, India from April-2022 to November-2022. All patients (n=278) visiting the ECG room with symptoms of chest pain, shortness of breath and past history of cardiovascular disease at the department of cardiology of the SMIH, Dehradun were included in the study. Results: Mean age (SD) was 53.96±15.31 years. The male gender participants was 75.17%. 14.3% were STEMI patients as per the standard 12 lead interpretation, smartphone ECG interpreted 7.1% of the participants as STEMI and cardiologist interpreted nearly 15.4% of the participants of STEMI. Conclusions: This study confirmed the potential of a smartphone ECG for evaluation of STEMI and the feasibility of studying this technology further to define the diagnostic accuracy, limitations, and appropriate use of this new technology.

Mahajan et al. (2023) conducted a cross-sectional in ST-elevation myocardial infarction (STEMI) (n=278). Spandan smartphone 12-lead ECG vs. Standard 12-lead ECG was evaluated on Sensitivity for STEMI diagnosis compared to cardiologist. The Spandan smartphone 12-lead ECG demonstrated 100% sensitivity and 81.4% specificity for detecting STEMI compared to a cardiologist's diagnosis, whereas the standard 12-lead ECG showed 91.8% sensitivity.
