Meet the man whose smartwatch saved his life when it alerted him to his dangerously low heart rate, after his heart stopped 138 times in 48 hours.
David Last, 54, received a new Apple watch from his wife, Sarah, 50, for his birthday in April. Straight away, the watch readings showed Last had a resting heart rate as low as 30 beats per minute, to as many as 2,885 times.
