September 1, 2026
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.
