So I’m in the hospital emergency room with a very aged relative with a dodgy ticker, and I’m doing what I can to offer some shred of comfort, stroking head, clasping hand, chatting about this and that.
And I’m looking at the digital monitor, displaying readings from various intensive care technology. And I watch as the arrhythmia, the irregular beating of the heart, clearly shows itself if you stop to look at the display for long enough.
