Cardiac conduction system necklace | sterling silver
The cardiac conduction system is the heart's own wiring. From the sinoatrial node in the right atrial wall, the impulse spreads across the atria to the AV node, down the bundle of His, and out across the Purkinje fibres that fire each ventricular contraction. The pendant traces that path.
The Science Behind the Conduction System
The cardiac conduction system begins at the sinoatrial (SA) node in the right atrial wall, the heart's natural pacemaker, generating 60 to 100 impulses per minute at rest. The impulse spreads across the atria to the atrioventricular (AV) node at the base of the right atrium, which introduces a brief delay (roughly 0.1 seconds) allowing atrial emptying before the ventricles contract. From the AV node the impulse travels down the bundle of His, divides into left and right bundle branches, and spreads through the Purkinje fibre network to activate ventricular myocardium in a coordinated, apex-to-base sequence. Disruption at any point produces characteristic ECG patterns: heart block, bundle branch block, pre-excitation syndromes, and re-entrant arrhythmias.
Who Tends to Wear This
- cardiologists, cardiac electrophysiologists, and cardiac device specialists
- arrhythmia specialists who ablate the abnormal pathways
- cardiac nurses and ECG technicians who interpret rhythms daily
- cardiology fellows working through their EP rotation
- patients who have had their own rhythm mapped or paced
Most often bought by people who can sketch the conduction pathway from memory.

FAQ
Will a cardiac electrophysiologist actually appreciate this?
Most do. Electrophysiology is one of the more visual subspecialties in cardiology. Every procedure involves mapping conduction pathways and reading ECG patterns. The conduction-system pendant is recognisable to anyone who has spent time looking at His-Purkinje activation patterns or 12-lead ECGs. The format reads as anatomical jewellery to non-cardiologists, which suits how most clinicians prefer to wear pieces from their field at work.
Why does the AV node introduce a delay?
The AV node is the only electrical bridge between the atria and the ventricles. Its conduction velocity is deliberately slow, around 0.05 metres per second compared to about 4 metres per second in the Purkinje fibres. The delay (roughly 0.1 seconds) gives the atria time to finish contracting and pumping blood into the ventricles before the ventricles themselves contract. Without that delay, atrial and ventricular contraction would overlap and the heart's pumping efficiency would collapse.
What size is the pendant and what does it ship with?
The pendant is in 925 sterling silver, nickel-free and hypoallergenic, sized to read clearly without overstating itself. It comes on a 45 cm sterling silver chain (1.8 mm width, lobster clasp) with a 5 cm extender. Free worldwide DHL Express shipping in 1-5 business days, all import duties covered, in a ready-to-gift jewelry box.
Is this available in gold vermeil?
Yes. The same conduction-system design is available in 18k gold vermeil at a slightly higher price. Most cardiologists pick the silver for daily wear in clinic. The gold tends to be the choice for graduations, board-passing, or fellowship completion, when someone wants the piece to mark a specific transition rather than sit on every day.
