T-Wave Oversensing with Contemporary Implantable Cardioverter-Defibrillators. [PDF]

J Cardiovasc Dev Dis, 2023
Background: Implantable cardioverter–defibrillators (ICDs) need to reliably detect ventricular tachycardia (VT) and ventricular fibrillation (VF) while avoiding T-wave oversensing (TWOS), which is associated with a risk of inappropriate therapies.

A case of inappropriate implantable cardioverter defibrillator therapy induced by T-wave oversensing due to hyperkalemia. [PDF]

J Arrhythm, 2015
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 ...

Clinical and electrocardiographic predictors of T wave oversensing in patients with subcutaneous ICD. [PDF]

J Arrhythm, 2016
Background: T wave oversensing (TWOS) is a major drawback of the subcutaneous implantable cardioverter defibrillator (S-ICD). Data on predictors of TWOS in S-ICD recipients are limited.

Strategies for overcoming T-wave oversensing. [PDF]

Indian Pacing Electrophysiol J, 2014
Atrial tachycardia/atrial fibrillation accounted for the majority of cardiac resynchronization therapy loss and inappropriate therapies. However, many programmable causes of cardiac resynchronization therapy loss and inappropriate therapies such as TWOS might also be detected.

Authors reply to 'strategies for overcoming T-wave oversensing'. [PDF]

Indian Pacing Electrophysiol J, 2014
In their letter to the editor Cay et al express some valid concerns regarding the strategy we described for overcoming T-wave oversensing in our patient. They stress that programmable features of the device should be used first before planning a reintervention.

Device rounds: T-wave oversensing: A cause of loss of cardiac resynchronization therapy [PDF]

Indian Pacing Electrophysiol J, 2016
A CRT-D patient presented with loss of biventricular pacing associated with heart failure symptoms. The electrocardiogram showed sinus rhythm with alternating wide unpaced and narrower paced QRS complexes.

T Wave Safety Margin during the Process of ICD Implantation As a Novel Predictor of T Wave Oversensing. [PDF]

Front Physiol, 2017
Introduction: T wave oversensing (TWOS) is a major drawback of implantable cardioverter defibrillator (ICD) and data on predictors of TWOS in ICD is limited.

P wave oversensing and rate-related bundle branch block with T wave oversensing leading to inappropriate S-ICD therapies in cardiac sarcoidosis: A case report. [PDF]

Indian Pacing Electrophysiol J
Subcutaneous implantable cardioverter defibrillators (S-ICDs) are increasingly implanted devices to prevent sudden cardiac death (SCD), whether as a primary or secondary prevention strategies especially in patients who are at risk of developing ...

Successful EV‐ICD Implantation After Removal of Both TV‐ICD and S‐ICD: A Case Report – “Third Time Is the Charm.”

Journal of Arrhythmia, Volume 42, Issue 2, April 2026.
We encountered a case in which an EV‐ICD was implanted following the extraction of a transvenous ICD due to systemic infection and subcutaneous ICD due to repetitive inappropriate shocks. The Florida Patient Acceptance Survey score was higher in the EV‐ICD. (A) Chest X‐rays for three types of implantable cardioverter‐defibrillators.

Single-Pocket-Incision Generator Exchange From a Subcutaneous to an Extravascular Implantable Cardioverter-Defibrillator. [PDF]

J Arrhythm
Subcutaneous‐to‐extravascular implantable cardioverter‐defibrillator exchange can create a practical challenge: the existing subcutaneous generator pocket lies posteriorly, whereas the new extravascular generator site is planned more anteriorly. In this case, fluoroscopic planning showed adjacent generator sites, allowing a single intervening pocket ...
