The Apple watch has saved the life of a 74-year-old woman with atrial fibrillation in her heart, making the heartbeat unstable.
She woke up in the middle of the night to wake up the Apple Watch, which she received as a gift from her grandchildren to monitor her heartbeat, with a heart rate of 157 at a time when the normal heart rate at rest ranges from 60 to 100 beats per minute.
The woman was taken directly to the hospital where her heartbeat was regulated by electric shocks after the valleys were unable to stabilize her condition.
More than 130,000 people die from atrial fibrillation if the patient's condition is not quickly monitored, according to the Centers for Disease Control and Prevention in Britain.
