Heartbeat

Heartbeat

Lying in intensive care
staring at the bleeping machines
fed by pulses
travelling along wires
connected to various parts of me
I see the curve of my heartbeat,
not sinusoidal like the mains,
thankfully not a straight line
(which I wouldn’t see),
but a complex waveform
repeating over and over
that can be approximated
using the arcane maths
of Fourier analysis.
This tells me that if God exists
he must be one helluva mathematician.
