Biotronik Implantable Cardioverter Defibrillator for Measurement of Intrathoracic Impedance: A Report of Two Cases
Year: 2024
Type: article
Study design: Case Report
Abstract: OBJECTIVES: Two patients were received ICDs (Biotronic Iforia7 VR-TDX). Holter analysis revealed pacing spikes, which occurred regularly at 100 ms intervals following QRS complexes, with consecutive 1024 test pulses at hourly intervals during a specific time, and the VP was 0%. METHODS: By analyzing the dynamic electrocardiogram and consulting relevant literature, it was found that this is a feature of the ICD that measures thoracic impedance. RESULTS: This phenomenon is a special function for the purpose of transthoracic impedance measurement, which can monitor the heart failure. CONCLUSIONS: This phenomenon should not be regarded as an interference signal or an abnormal sign of pacemaker malfunction.
