| 520 | 3 | |a Commercially available cardiac pacemakers and implantable cardioverters/defibrillators (ICD) predominantly use the intracardiac derived electrocardiogram (ECG) for detection of arrhythmias. To achieve an automatic control of the heart frequency in accordance with cardiovascular strain and an improved detection of life-threatening arrhythmias, it is desirable to monitor the heart by an input signal correlated with the hemodynamic state. One possible approach to derive such a signal, is to measure the inotropy (mechanical contraction strength of the heart muscle). For this purpose an optoelectronic measurement system has been designed. The fundamental function of the system has been shown in earlier investigations using an isolated beating pig heart. In this paper further results showing the correlation of the fiberoptic sensor signal with the left ventricular stroke volume are presented. To make the system useful for implantable devices, further improvements with regard to power consumption and signal quality were achieved. Zur Zeit auf dem Markt befindliche Herzschrittmacher und implantierbare Defibrillatoren (ICD) verwenden zur Erkennung von Arrhythmien überwiegend das im Herzen abgeleitete EKG. Um eine der Herz/Kreislauf-Belastung angepasste Regelung der Herzfrequenz bzw. eine verbesserte Erkennung von lebensbedrohlichen Arrhythmien zu ermöglichen, ist es wünschenswert, den hämodynamischen Status des Herzens als weitere Eingangsgröße messen zu können. Ein möglicher Ansatz zur Bestimmung einer solchen Größe ist die Messung der Inotropie (mechanische Kontraktionskraft des Herzmuskels). Zu diesem Zweck wurde ein optoelektronisches Messsystem entwickelt. Die grundlegende Funktion des Systems konnte in vorangegangenen Untersuchungen an isoliert schlagenden Schweineherzen nachgewiesen werden. In dem vorliegenden Beitrag werden weitergehende Ergebnisse zur Korrelation des Sensorsignals mit dem linksventrikulären Schlagvolumen dargestellt. Um das Sensorsystem für implantierbare Geräte nutzbar zu machen, wurden weiterhin Verbesserungen im Hinblick auf die Leistungsaufnahme sowie die Signalqualität vorgenommen. | |
