REAL stories, in their OWN words. I had an appointment with a cardiologist today. I printed my ECGs from this ECG+ app. The cardiologist's response was: "wow, this just saved us such an amount of time and research". He could immediately see the direction he should be looking further into. Hans_vdk · Belgium · 19 Mar 2024 ○ Accurate reading I am a retired Paramedic and can read ECGs very well. I knew I was having an irregular heart rhythm so I downloaded this ecg+ app and printed out my latest one lead ECG. I went to the Emergency Room with the print out, ecg+ was spot on and matched the 12-lead in the ER. The ER doc was quite impressed with the interpretation and print out. Code 3 2020 · United States · Retired Paramedic · 14 May 2024 =================== ECG+ analyzes your Apple Watch ECG to unlock the crucial cardiac details hidden inside, then creates a report with clear evidence of what happened, ready to bring to your doctor. Findings include patterns such as possible early, or premature, heartbeats, which some people notice around moments of sudden palpitations or skipped heartbeats, and burdens associated with premature beats and AFib. Most importantly, ECG+ tracks these findings for your peace of mind, so you know when things are under control or when your attention is needed, for example when premature beat burden is rising. ECG+ does not diagnose symptoms or medical episodes. Instead, it presents your recorded ECG data in a clearer, more structured way, so you can have a more informed and productive conversation with your doctor. Many users, including medical professionals, have found real value in ECG+. ○ Advanced readings to help your cardiologist Today I showed my doctor several ECGs derived from my Apple Watch through ECG+ and advanced data analysis. He was really impressed and helped answer a lot of my questions on PACs and PVCs. Apple ECG alone will not identify enough of what's going on. Highly recommend this app. MachKing · United States · 22 Mar 2024 ○ Very accurate As a CT ICU nurse of 34 years I find the readings on the EKG app to be surprisingly accurate! I'm very impressed with the quality of the telemetry given that it's from a watch on my wrist. It's also quite reassuring as I get older to know that it can automatically monitor for arrhythmia so I can be more proactive in following up with my physician on my heart health. Miramichigael · United States · CT ICU nurse, 34 years · 5 May 2024 [Intuitive designs] Every finding is marked directly on the ECG, with the supporting measurements laid out in one clear report: Premature beats - the skipped, extra or fluttering beats you actually feel Rhythm patterns - bigeminy, trigeminy, quadrigeminy, couplets and triplets, marked where they happen Premature-beat burden - how often abnormal beats occur, tracked over time QT / QTc interval measurements Heart Rate Variability (HRV) - with its trend, shown as a Poincaré plot AFib irregularity - the irregularly-irregular pattern that points to atrial fibrillation [HealthKit] ECG+ integrates with Apple Health through HealthKit, making it easy to access your Apple Watch ECG recordings without manual imports.
