ECG+ | Your Watch ECG Reader

Premature beats are often benign, but their symptoms can be unsettling, and the anxiety they cause may make the experience feel worse. ECG+ now looks more deeply at your Journal and Sleep data to help uncover patterns and identify possible triggers, to help you better control them. Every finding in ECG+ is supported by evidence. When a beat is labeled A rather than V, there is a specific reason. In version 1.17.5, you can now explore the evidence behind each finding, including beat timing and waveform morphology, with clear explanations throughout. Your doctor can also review these details and discuss what they mean with you.

“So what triggered my AFib?” Now, ECG+ can help you get closer to an answer. Maybe it was the long dinner and a little too much wine. The quick climb upstairs. Bending down. A late night. Or the quiet moment just after you slipped into bed. Then came the flutter. Your Apple Watch captured the rhythm. Your doctor helped put a name to it. But one question remained: why then? ECG+ v1.17.4 introduces the new Trigger Card for AFib recordings, helping you narrow down which events may have triggered your episodes. It cannot prove a cause, but it may reveal a pattern worth discussing with your doctor.

Thirty seconds of recording. Now with the story around it. What a recording shows often starts hours before it: the short sleep, the third coffee, the stressful call, the flutter you felt on the stairs. ECG+ now keeps a Journal beside every recording. Symptoms and possible triggers in two taps, a note in your own words, your sleep drawn in from Apple Health. It changes what your questions get back. Ask AI about a recording and it answers with the complete picture, beats and context together, the way a good doctor thinks. And when you do sit across from your cardiologist, you arrive with their first question already answered, recording by recording. The more context you give, the more complete the picture, the more accurate the explanation, and the more informed the conversation with your doctor.

Adaptive AI explanations ECG+ now works with Claude to explain your ECG reports, and nothing changes in how you use it. You don't need to pick a model. ECG+ chooses the right one for each report and sends the more eventful recordings to a stronger model, which is included at no extra cost. Your typical heartbeat With enough recordings in a month, ECG+ picks the best candidates and summarizes them into your typical heartbeat, far more reliable than reading any single beat.

More accurate and honest measurements An upgraded measurement engine (v1.18) reads waves more faithfully. When a wave cannot be reliably identified, for example a P wave with very low amplitude, instead of throwing a bunch of numbers around, ECG+ now marks the area it searched and explains why it's not a good idea to measure an unclear wave. This is often seen on recordings with lots of artifacts (noise) caused by poor contact. Search your recordings Find any recording in seconds. Search by symptoms, triggers, notes, or findings.
