We’ve made several behind-the-scenes improvements to enhance performance and reliability. While most updates aren’t visible, advanced users can now manually adjust T wave identification for greater control in ECG analysis.

This update includes a critical correction to QTc over-estimation caused by T wave elevation. Unlike traditional approaches that rely on the isoelectric line, the tangent method identifies the true T wave baseline, reflecting your heart’s real repolarization. This improved algorithm now ensures more accurate QTc calculations, enhancing the reliability of ECG analysis.

A huge Thank You to everyone who shared their ECG data to help us make these improvements! Your support drives us forward.

In Version 1.9.6, we’re thrilled to roll out the Export Your ECGs feature! Now, you can export your ECG data to a CSV file, which includes detailed measurements for each reading—such as PR, QRS, QT, and RR intervals—along with five QTc calculation options: Bazett, Fridericia, Framingham, Hodges, and Rautaharju. This range of QTc formulas allows you to choose the method that best aligns with your needs or healthcare recommendations.

The CSV format is designed to make it easy for you to track trends, perform your own analysis, or share data with healthcare providers, helping you take an active role in monitoring and understanding your heart health.

ECG+ interprets your Apple Watch ECGs to detect more potential arrhythmias and abnormalities.

◆ Atrial Fibrillation Detection: Identifies the most common arrhythmia that often requires medical attention.
◆ PAC/PVC Identification: Recognizes common but typically benign heart conditions.
◆ Prolonged QT Interval Alerts: Highlights prolonged QT intervals, indicating potential delays in heart recharging.
◆ T Wave Changes: Detects inverted or flattened T waves, which may suggest underlying health issues.
◆ HRV Monitoring: Tracks Heart Rate Variability (HRV), a key indicator of overall wellbeing.

The latest version of ECG+ includes a new Heartbeat Navigator, designed to help users quickly locate abnormal heartbeats, such as PACs or PVCs, for more efficient analysis. This powerful tool enhances the user experience, making heart monitoring more intuitive and effective.

Additionally, the app now offers advanced detection for T wave abnormalities. Capable of identifying both flattened and inverted T waves, ECG+ provides essential insights into possible heart conditions, supporting early detection and proactive health management. This upgrade allows users to monitor their heart health with increased precision and confidence.
