Experience the next level of heart health monitoring with our cutting-edge ECG analysis app. Seamlessly sync your Apple Watch ECG readings for in-depth analysis that goes beyond the surface. Our advanced algorithms detect and interpret ECG waves, providing comprehensive insights into your heart's rhythm, including P, QRS, and T waves, as well as QTc intervals. With enhanced functionality, you can now visualize the average template beat, edit its delineation, and track key intervals like P, QRS, T, and QTc. The app also provides powerful tools for heart rate variability (HRV) analysis, including both frequency and time domain views, along with a Poincare Plot to explore HRV trends in a unique way. Additionally, the HRV histogram helps you understand the distribution of heart rate variability over time. The Signal View now displays the duration of each detected interval (e.g., P, QRS, T) in milliseconds (ms), making it easier to track and compare these key heart rhythm markers. Customize thresholds for intervals such as P, QRS, QT, and QTc, and receive real-time alerts when your readings fall outside these ranges, helping you manage your heart health more proactively. Track changes over time and gain a deeper understanding of your heart health journey. Share your ECG data with your healthcare provider for tailored advice and support. Important: This app is not a substitute for professional medical advice, diagnosis, or treatment.
