Biotronik Implantable Cardioverter Defibrillator for Measurement of Intrathoracic Impedance: A Report of Two Cases
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%.

| Summary: | 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. |
