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

Journal of Arrhythmia
Introduction Extravascular implantable cardioverter‐defibrillator (EV‐ICD) is a novel therapy with a high‐voltage lead implanted in the substernal space.

Combined Application of a Helix-Fixation Leadless Pacemaker and a Subcutaneous Implantable Cardioverter-Defibrillator in a Dialysis Patient: A Case Report. [PDF]

Clin Case Rep
ABSTRACT Combined use of S‐ICD and LP provides an effective alternative for patients requiring defibrillation and pacing while avoiding transvenous leads. This strategy is particularly valuable for patients with a high risk of infection, though careful consideration must be given to minimizing potential device–device interactions.

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 ...

Strategies for Overcoming T-Wave Oversensing

Indian Pacing and Electrophysiology Journal, 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.

Does an Implantable Cardiac Monitor Always Tell the Truth? A Case of an Underestimated Prolonged Pause Episode

Journal of Arrhythmia
A graphical summary of the mechanism underlying the underestimation of a prolonged pause episode by an implantable cardiac monitor (ICM). This case illustrates that ICM episode summaries may underestimate clinically significant pauses, underscoring the importance of electrogram review and remote monitoring for accurate diagnosis.

Authors Reply to ‘Strategies for Overcoming T-Wave Oversensing’

Indian Pacing and Electrophysiology Journal, 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.

Atrial Tram Tracks and Ventricular Step Ladder: Decoding the Dot Plot. [PDF]

J Arrhythm
Falsely detected atrial tachycardia episode in a patient with CRT‐P due to FFRW oversensing resulting in ventricular sensed response triggered BiV pacing and auto adjusting sensitivity phenomenon.

Lead Integrity Alert Triggered by T-wave Oversensing [PDF]

Journal of Innovations in Cardiac Rhythm Management, 2020
T-wave oversensing (TWOS) is a relatively common occurrence in pacemakers and defibrillators that can lead to pauses and inappropriate implantable cardioverter-defibrillator shocks. We present a case of TWOS that triggered the Lead Integrity Alert (Medtronic, Minneapolis, MN, USA) without evidence of actual lead failure.

Loss of biventricular pacing due to T-wave oversensing [PDF]

Europace, 2010
The benefits obtained with cardiac resynchronization therapy are directly related to the occurrence of continuous biventricular pacing. We report a case of intermittent loss of biventricular pacing due to ventricular oversensing that worsened the functional status of the patient.

Polarization Potentials Causing Pacemaker Oversensing

Japanese Circulation Journal, 1998
Pacemaker oversensing with inappropriate inhibition is commonly caused by sensing of either T-waves or polarization potentials, which are difficult to distinguish from one another. Decisive evidence, obtained from telemetered electrograms and subthreshold pacing, is presented to support sensing of the polarization potential alone and the exclusion of ...
