00:00A pacemaker not only has the ability to create a heartbeat, trigger the heart to beat,
00:06but it's also a sophisticated monitor of the patient's heart rhythm.
00:11And a pacemaker is programmed to check in once a day,
00:16just to check in with its communication device and then ultimately the app that monitors it once a day.
00:22Typically that's at night.
00:23So at 2 o'clock in the morning, that's all it might have been doing.
00:27The other possibility is that it actually might have detected an arrhythmia.
