Performance Metrics

EMAY Portable ECG Monitor

Eko DUO (ECG + Stethoscope)

ECG Accuracy

Measures how closely the device's rhythm recordings match clinical gold-standard ECG machines.

Provides a clean 250 Hz single-lead signal; however, automated interpretations are intended for reference only and can be sensitive to motion artifacts.

The 1-lead ECG provides a crisp, clinical-grade waveform suitable for rhythm analysis, validated for AFib detection through the Eko analysis suite.

+10% better ecg accuracy

Arrhythmia Detection Accuracy

The ability of the device to correctly identify various heart rhythm abnormalities.

Capable of detecting up to 12 cardiac situations including AFib and PVC patterns, though accuracy depends heavily on user stillness during the 30-second window.

Validated for the detection of Atrial Fibrillation and Normal Sinus Rhythm via automated analysis.

AFib Detection Sensitivity

How reliably the device identifies Atrial Fibrillation when it is present.

Identifies A-Fib markers effectively in stable waveforms; however, the lack of clinical-grade clearance for primary diagnosis means results must be physician-verified.

Highly sensitive detection when using the Eko AI, though dependent on a clear, low-noise ECG signal.

+8% better afib detection sensitivity

ECG Signal Quality

The clarity and stability of the ECG trace, minimizing interference and noise.

The 250 dots/s recording rate provides adequate detail for rhythm assessment, with an 'Orange to Green' indicator to signal a stable recording environment.

Stainless steel electrodes and digital filtering ensure a very high signal-to-noise ratio during auscultation.

Clinical-Grade Correlation

The degree to which the device's output correlates with professional hospital equipment.

Correlates well with basic clinical Lead I rhythm strips for heart rate and rhythm identification but lacks the diagnostic validation of 6-lead or 12-lead systems.

Acoustic and electrical performance meets or exceeds requirements for clinical diagnostic use.

Expert Review Summary

Our clinical assessment and verdict for each device

EMAY Portable ECG Monitor

Worth Considering

"The EMAY Portable ECG Monitor is a highly accessible, standalone tool for those who want a simple way to monitor heart rhythm without being tethered to a smartphone."

The EMAY Portable ECG Monitor (EMG-20) is a single-lead, handheld device designed for the intermittent recording of Lead I ECG signals. Its primary strength is its standalone functionality; unlike many competitors, it features a built-in 1.77-inch color TFT-LCD screen that displays the real-time ECG waveform and heart rate during a 30-second recording session. Once complete, the device provides an instant analysis of the rhythm across 12 different categories, including AFib, Bradycardia, Tachycardia, and ST-segment changes. While the manufacturer explicitly states it is for 'initial evaluation' and not a substitute for clinical diagnostics, its 250 Hz sampling rate and clinical safety compliance (IEC 60601-1) make it a reliable reference tool. Data management is flexible, offering both a Bluetooth-connected mobile app for iOS and Android and a dedicated PC/Mac software for detailed report generation. Its memory capacity for 100 readings on-device and long-lasting rechargeable battery (~360 measurements per charge) make it a practical companion for health-conscious users who prefer physical controls and immediate visual feedback.

Eko DUO (ECG + Stethoscope)

Highly Recommended

"The Eko DUO is an indispensable hybrid device for clinicians and high-risk patients, offering amplified heart sounds and synchronized ECG data in a single, streamlined interface."

The Eko DUO (ECG + Stethoscope) represents a significant advancement in bedside diagnostic technology. It combines a 1-lead ECG with a high-fidelity digital stethoscope, allowing for the simultaneous assessment of electrical and mechanical heart function. The device provides up to 60x sound amplification and features advanced background noise reduction, which is critical for identifying subtle murmurs or gallops in loud clinical environments. The integrated ECG electrodes capture a Lead I rhythm strip that is transmitted via Bluetooth to the Eko App for real-time visualization and analysis. The DUO is specifically designed to work with Eko's FDA-cleared AI algorithms, which can screen for Atrial Fibrillation and heart murmurs with high sensitivity. While it is a single-lead device, the correlation between the acoustic and electrical data provides a depth of insight typically only found in much larger clinical systems. Its wireless charging capability and pocket-sized form factor make it highly practical for daily rounds or home-based monitoring under medical supervision.
