ISiK Basis Implementierungsleitfaden

Resource Profile: ISiKEKG

Official URL: https://gematik.de/fhir/isik/StructureDefinition/ISiKEKG Version: 6.0.0-rc
Active as of 2026-04-02 Computable Name: ISiKEKG

Dieses Profil spezifiziert die Minimalanforderungen für die Bereitstellung von Informationen über kurze, relevante EKG-Ausschnitte eines Patienten im Rahmen der interoperablen Kommunikation gemäß den Vorgaben der ISiK. Es wurde entwickelt, um spezifische klinische Fragestellungen zu unterstützen, bei denen prägnante und gezielte EKG-Daten im Vordergrund stehen. Für vollständige und längere EKG-Aufzeichnungen sind alternative Formate vorgesehen, die für umfangreiche Daten besser geeignet sind.

Motivation

Die Bereitstellung kurzer EKG-Ausschnitte ermöglicht eine präzise und effiziente Unterstützung bei der Diagnose akuter kardiologischer Fragestellungen, der Überwachung von Arrhythmien oder der Beurteilung bestimmter Ereignisse wie ST-Strecken-Veränderungen. Diese fokussierte Darstellung dient der Optimierung klinischer Entscheidungen und der schnellen Verarbeitung relevanter Daten.

In FHIR wird das EKG durch die Observation-Ressource repräsentiert, wobei spezifische Anforderungen für die Darstellung und Kodierung der Daten in diesem Profil berücksichtigt werden.

Kompatibilität

Das Profil ISiKEKG ist vom Profil EkgDE aus den deutschen Basisprofilen abgeleitet.
