Wearable technology saves lives through early detection

Summary: A 94-year-old doctor, who spent his career promoting early cancer detection, used his Apple Watch to save his own life. Waking up with chest discomfort, he checked his watch's ECG app and saw his heart rate had dropped to a dangerous 40 beats per minute. While he wanted to see his regular heart doctor, his wife insisted they go straight to the emergency room. Doctors discovered a complete heart block and quickly put in a pacemaker. He credits the smartwatch—and his wife's quick thinking—for saving him.
