Implantable Cardioverter Defibrillator and Inappropriate Therapy: “Black Box” Examination Yielded Both Human and Technical Causes

چکیده
We report on a 70-year-old male patient who was recipient of GEM III DR 7275 Cardioverter Defibrillator, and who presented with inappropriate shocks. The patient had a documented slow ventricular tachycardia (VT), and the device was programmed to detect VT at rates >100 bpm, fast VT (FVT, via VT) at rates >150 bpm, and ventricular fibrillation (VF) at rates >188 bpm. After detection of FVT, efficient therapy was delivered; however, this was immediately followed by multiple inappropriate therapies. Inappropriate therapies were discussed, with a focus on programming features.

Implantable cardioverter-defibrillator in a patient with dextrocardia situs inversus
Background: Dextrocardia is a congenital anomaly, which may have coexistent coronary artery disease (CAD), arrhythmias and conventional indications for device therapy. However, the implantation of transvenous leads can be technically challenging and the approach needs to be tailored to the patient's individual anatomy. Case presentation: A 54-year-old male with dextrocardia situs inversus and i...

متن کاملA case of inappropriate implantable cardioverter defibrillator therapy induced by T-wave oversensing due to hyperkalemia.
There have been reports of hyperkalemia-induced T-wave oversensing in patients with implantable cardioverter defibrillators (ICDs). However, a comparison of T-wave amplitudes and morphologies between the surface 12-lead electrocardiogram (ECG) and ICD electrogram has not been reported. We present the case of a 70-year-old man who received inappropriate ICD shocks due to hyperkalemia-induced T-w...
متن کاملTrouble Shooting of ICD Therapy: Inappropriate Shock
Patients with an implantable cardioverter defibrillator (ICD) can undergo inappropriate therapies (shock or antitachycardia pacing) if electrical activity not originating in the ventricle is wrongly recognized as ventricular by the device. Inappropriate therapy leading to shocks is not innocuous; consequences include pain and its psychological sequelae, particularly anxiety, as well as inductio...
متن کاملTwo cases of inappropriate implantable cardioverter-defibrillator therapies due to T wave oversensing induced by body twisting
T wave oversensing (TWOS) is a common cause of inappropriate implantable cardioverter-defibrillator (ICD) therapies. Various algorithms to avoid inappropriate ICD therapy are available; however, they are not helpful to avoid TWOS. Although the reproduction of TWOS is useful to resolve the problem of TWOS, it is sometimes difficult to reproduce TWOS. We report two cases of inappropriate ICD ther...
