Two cases of inappropriate implantable cardioverter-defibrillator therapies due to T wave oversensing induced by body twisting

Journal of Arrhythmia, 2017
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.

Inhibition of the Oversensing of Cardiac Pacemakers in Chest CT

Open Journal of Medical Imaging, 2012
Objectives: The purpose of this study is to identify how to manage oversensing of pacemakers in chest CT. Methods: Four different models of pacemakers were examined to select the pacemaker generating oversensing. To the pacemaker with oversensing, intermittent switching X-ray was exposed using ECG-gated CT helical scan system at prospective CTA mode ...

Inappropriate Shock Delivered By Implantable Cardioverter Defibrillator - Cardiac Resynchronization Therapy (ICD-CRT) Due To Myopotential Oversensing

Indian Pacing and Electrophysiology Journal, 2009
The clinical efficacy of ICD-CRT therapy depends on accurate sensing of intracardiac signals and sensing algorithms. We report the occurrence of sensing abnormality in a patient with ICD-CRT. In this patient, oversensing of myopotentials during strenuous

Importance of exercise testing shortly after subcutaneous implantable cardioverter-defibrillator implantation in patients with Brugada syndrome – The first case of associated inappropriate shock in Japan

Journal of Arrhythmia, 2017
We report the case of a 51-year-old patient with Brugada syndrome (BrS) who experienced inappropriate shock due to T-wave oversensing (TWOS) during exercise when the optimal sensing vector was selected based on the automatic analysis by a subcutaneous ...

An inappropriate defibrillator shock during ventricular tachycardia

Indian Pacing and Electrophysiology Journal, 2015
Ventricular oversensing in patients with defibrillators is an infrequent but deleterious condition. We report a patient with a cardiac resynchronization–defibrillation device that presented with hyperkalemia and syncope.

T wave oversensing in subcutaneous implantable cardioverter defibrillator secondary to hematoma formation: A potential cause of early postimplantation inappropriate shocks

Journal of Arrhythmia, 2019
T wave oversensing (TWOS) is the most common cause of inappropriate shocks in subcutaneous cardioverter‐defibrillators (S‐ICD). We are presenting a patient with severe ischemic cardiomyopathy who received a S‐ICD while on antiplatelets therapy.

Inappropriate mode switching clarified by using a chest radiograph

Journal of Arrhythmia, 2015
An 80-year-old woman with a history of paroxysmal atrial fibrillation and atrioventricular node disease status post-dual chamber pacemaker placement was noted to have abnormal pacing episodes during a percutaneous coronary intervention.

Subcutaneous Implantable Cardioverter Defibrillator in Patients With Hypertrophic Cardiomyopathy: An Initial Experience

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundThe subcutaneous implantable cardioverter defibrillator (S‐ICD) has been developed to avert risks associated with transvenous defibrillator leads. The technology is attractive for younger patients, such as those with hypertrophic cardiomyopathy
