Postural change-dependent T-wave oversensing resulting in the administration of inappropriate shocks [PDF]
Journal of Arrhythmia, 2012 A 68-year-old man with dilated cardiomyopathy (left ventricular ejection fraction, 15%) and nonsustained ventricular tachycardia received an implantable cardioverter defibrillator. Even though his cardiac status had greatly improved 2 years later after β-

Hyperglycemia-Induced T-Wave Oversensing as a Cause of Cardiac Resynchronization Therapy (CRT) Failure [PDF]
Journal of Tehran University Heart Center, 2012 T-wave oversensing occurs when the counter starts giving dual beeps for every cardiac cycle instead of one. This usually happens when the monitoring lead displays a tall T wave, which is also sharp. R wave sensing algorithms of the devices do not sense T

T-wave oversensing and inappropriate shocks: a case report [PDF]
Europace, 2008 A 27-year-old male with congenital long QT syndrome, SCN5A mutation experienced recurrent inappropriate exercise-related implantable cardioverter defibrillator (ICD) shocks. This device showed T-wave oversensing with double, which lead to these device discharges. Dynamic T-wave oversensing was reproducibly provoked at exercise treadmill testing and was

Strategy to manage T-Wave Oversensing in a Biventricular ICD [PDF]
International Journal of Cardiovascular Practice, 2017 T-wave oversensing is a relatively prevalent cause of intracardiac signals oversensing in patients with Implantable Cardioverter Defibrillator (ICD). Some of these oversensings are typically corrected with device reprogramming. If reprogramming fails to resolve the issue, invasive options such as repositioning the implanted lead may be necessary.

Intermittent failure of pacing output caused by algorithm to prevent T-wave oversensing. [PDF]
HeartRhythm Case Rep, 2016 Oversensing of extracardiac myopotentials can lead to pacemaker inhibition and loss of cardiac output. We describe 2 similar cases in which oversensing of myopotentials and loss of pacemaker output in pacemaker-dependent patients was caused by a proprietary algorithm designed to prevent T-wave sensing.

Left and Right Ventricle Leads Switch as a Solution for T Wave Oversensing - How a Good Idea Turned Out Bad [PDF]
Indian Pacing and Electrophysiology Journal, 2014 A 50-year-old male with a CRT defibrillator received inappropriate ICD shocks due to T-wave oversensing. Decreasing the sensitivity to avoid T wave oversensing was not an option due to a suboptimal R-wave sensing amplitude.

T wave oversensing in subcutaneous implantable cardioverter defibrillator secondary to hematoma formation: A potential cause of early postimplantation inappropriate shocks. [PDF]
J Arrhythm, 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.

Two cases of inappropriate implantable cardioverter-defibrillator therapies due to T wave oversensing induced by body twisting. [PDF]
J Arrhythm, 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.
