Systema conducente cordis · Převodní systém srdeční
Nervous system
Looks like
A thread of specialised muscle: a node in the right atrium, a relay, and branches down the septum.
What it does
Sets the heartbeat and carries it so the chambers squeeze in order.
Keeping it well
Potassium and thyroid in range, limit alcohol; a slow, fast or irregular pulse with dizziness needs a trace.
