Apple Watch’s ECG heart sensor saved a man’s life by sending him alerts for a low resting heart rate on almost 3,000 occasions

David Last, 54, from the UK credited Apple Watch for saving his life

His heart resting rate was found to have dropped as low as 30 beats per minute 

After tests like a 48-hour ECG and MRI, his cardiologist told him that he had a massive heart blockage

His heart stopped 138 times in 10-second intervals over a 48-hour ECG period

Last was operated this month, and a pacemaker was installed to detect abnormal heart rhythms

His wife gave him Apple Watch as a gift on his birthday in April this year

The Apple Watch has saved several lives in the past across the world
