Backups in the Conduction System
The sinoatrial node sets the pace, but it is not the only part of the conduction system with a rhythm of its own. Cells in the atria, the atrioventricular node and the bundle of His can start a beat too, and so can the Purkinje fibres in the ventricles. They stay quiet because the faster signal from above keeps reaching them first and holds them back, an effect called overdrive suppression. If that signal stops coming through, a site further down takes over, each one slower than the last: the AV junction at roughly 40 to 60 beats a minute, the ventricles at about 20 to 40. The heart keeps spares for its pacemaker, and spares for the spares.

FAQ
How big is it, and how does it sit?
The pendant measures 35 mm (about 1.4 inches), about 9 mm more than the width of a 2-euro coin. It hangs from a loop on a 45 cm (17.7 inch) gold vermeil chain with a 5 cm (2 inch) extender and sits on the upper chest. Extra chains in 40, 42, 45 and 50 cm (each with a 5 cm extender) and 80 cm can be added on this page. It is 2.5 microns of 18K gold over solid sterling silver, nickel-free and hypoallergenic.
Does it come in silver?
Yes. The same cardiac conduction system necklace comes in sterling silver, also 35 mm, on a sterling silver chain of the same length with the same 5 cm extender, and it hangs from a loop in the same way. Choose the finish the recipient already wears: the design is the same in both.
Will it arrive in time, and what if it isn't right?
DHL Express delivers free in 1-5 business days worldwide, and we pay the import duties and taxes, so nothing is due at the door. It arrives in a ready-to-gift jewelry box and festive envelope. If it isn't right, our 30-day “Love It or Return It” policy applies.
Who pushed for the first fully implanted pacemaker?
Else-Marie Larsson, in Stockholm. Her husband Arne, 43, had a heart that beat so slowly he kept losing consciousness. She read a newspaper article about an implantable pacemaker that the physician and engineer Rune Elmqvist and the surgeon Åke Senning had tried only in animals at the Karolinska Hospital, and persuaded them to try it on him. Senning implanted it on 8 October 1958. That device stopped within hours and a second one replaced it. Arne lived to 86, outliving both Elmqvist and Senning.
