Abstract

This paper describes an electronic model of the conduction system of the heart, in the form of a simulation unit for cardiac arrhythmias. The basic assumptions made are the existence of two distinct cardiac pacemaking centres, and the possibility of reciprocal interaction between them. Details concerning the construction of the simulation unit are given, and its operation is illustrated by means of a few simple examples of cardiac arrhythmias. The advantages presented by this device for teaching and demonstration of various cardiac arrhythmic patterns are also emphasized.

Sommaire

Ce mémoire décrit un modèle électronique du système de conduction du coeur, sous la forme d'une unité de simulation pour les arythmies cardiaques. Les suppositions de base faites sont l'existence de deux centres cardiaques distincts pour le règlement de l'allure cardiaque et la possibilite d'une interaction réciproque entre eux. Des détails concernant la construction de l'unité de simulation sont donnés et son opération est illustrée avec l'aide de quelques exemples simples d'arythmies cardiaques. Les avantages présentés par cet appareil pour l'instruction et la démonstration des types d'arythmie cardiaque variés, sont aussi soulignés.

Zusammenfassung

In dieser Abhandlung wird ein elektronisches Modell des Kardia-Leitsystems beschrieben. Es beruht auf der grundsätzlichen Annahme der Existenz zweier, verschiedener Keith-Flackscher Knotenzentren und der Möglichkeit einer gegenseitigen Wechselaktion zwischen denselben. Es werden Konstruktionseinzelheiten des Simulierapparates angegeben und seine Leistungsfähigkeit durch vereinzelte Beispiele von Herzarrhythmie illustriert. Die Vorteile dieser Vorrichtung für den Unterricht und die Vorführung verschiedener kardiakarrhythmischer Beispiele werden hervorgehoben.
