AI Verdict

Tempus ECG-Low EF is designed for clinical settings, analyzing 12-lead ECGs to detect signs of low left ventricular ejection fraction, aiding clinicians in heart failure risk assessment. In contrast, the Withings ECG App is an over-the-counter mobile solution for consumers, utilizing single-channel ECGs from a smartwatch to detect atrial fibrillation, sinus rhythm, and high heart rate. While both leverage AI for cardiac health, their distinct focus areas, deployment models, and target users make them complementary rather than directly comparable.

Choose Tempus ECG-Low EF if…

Choose Tempus ECG-Low EF if your clinical practice needs an FDA-cleared AI solution to analyze 12-lead ECGs within healthcare facility workflows, specifically to detect signs associated with low left ventricular ejection fraction (LVEF ≤40%) in at-risk patients 40 years or older. This tool is designed to aid clinicians in the early identification and further evaluation of potential heart failure cases in a diagnostic setting.

Frequently Asked Questions

What are the primary clinical applications for each tool?

Tempus ECG-Low EF is an AI software designed to analyze 12-lead ECGs to detect signs associated with low left ventricular ejection fraction (LVEF u226440%) in patients 40 years or older at risk of heart failure. The Withings ECG App, integrated with ScanWatch, enables users to record single-channel ECGs for the detection of atrial fibrillation (AFib), sinus rhythm, and high heart rate.

What type of ECG data does each tool analyze?

Tempus ECG-Low EF analyzes resting, non-ambulatory 12-lead ECG recordings collected in a healthcare facility. In contrast, the Withings ECG App records single-channel ECGs, equivalent to Lead I, through compatible Withings ScanWatch devices for over-the-counter (OTC) use.

What patient populations or use cases are most appropriate for each tool?

Tempus ECG-Low EF is intended for patients 40 years or older at risk of heart failure, aiding clinicians in further evaluation. The Withings ECG App is for over-the-counter (OTC) use by individuals 22 years or older, enabling them to monitor for AFib, sinus rhythm, and high heart rate, and share data with their healthcare professionals.
