Apple has released another entry in its ongoing series of Apple Watch "true stories," featuring a triathlon runner whose life was saved after the device's ECG app detected a cardiac condition.

In the video "ECG: Connor's True Apple Watch Story," Connor recounts how, while completing a challenging triathlon, he noticed his heart rate reaching 219 beats per minute. Concerned, he used the ECG feature on his Apple Watch, which identified atrial fibrillation. The alert prompted him to seek medical attention, leading to the discovery of an underlying heart condition he was previously unaware of.

Following the diagnosis, Connor underwent open heart surgery and now describes feeling "almost like I've got a new engine." He expressed deep gratitude for the Apple Watch, stating, "I can't say enough good things about the Apple Watch. It's amazing."

The new series of videos takes a more personal approach, shot to resemble user-generated content rather than Apple's typical polished productions. This follows a previous story featuring Phil, whose Apple Watch's Fall Detection automatically called for help after a biking accident that broke his collarbone.
