After-Potential Oversensing by a Programmable Puise Generator
PACE - Pacing and Clinical Electrophysiology, 1981Oversensing and recycling due to pacemaker stimulus after‐potentials are recognized complications of non‐competitive pacing. Often mas‐querading as T‐wave sensing, after‐potential oversensing may result in slowing or acceleration of pacing rate. We report two cases of after‐potential oversensing in po‐tients with R‐wave inhibited (VVI) programmable ...

The Clinical Relevance of Electromyopotential Oversensing in Current Unipolar Devices
PACE - Pacing and Clinical Electrophysiology, 1992Electromyopotential Oversensing of unipolar pacemakers was first appreciated 20 years ago, but its prevalence in present day devices is less well defined. Thirty‐four pacemaker patients, only two with symptoms suggestive of Oversensing, were evaluated in unipolar settings to assess the frequency of provocation of oversensing in one or, if present, both

A 55-year-old woman with a single chamber pacemaker presents to clinic for her 1-month post-implant visit. She has a history of coronary artery disease and presented to an outside facility with complete heart block 5 weeks ago in the setting of an acute coronary syndrome. Her escape rhythm at the time consisted of an accelerated junctional rhythm at 65

P Wave Oversensing in a Unipolar VVI Pacemaker
Pacing and Clinical Electrophysiology, 1995A 45‐year‐old male had a WI pacemaker implanted 20 years ago because of complete heart block. Because of perforation of the lead the pulse generator was removed after 4 weeks and a second lead was implanted from the contralateral side. Recently, the patient presented with symptoms of lightheadedness and syncope associated with prolonged pauses in the ...

PACE - Pacing and Clinical Electrophysiology, 2003
WERETKA, S., et al. : Ventricular Oversensing: A Study of 101 Patients Implanted with Dual Chamber Defibrillators and Two Different Lead Systems. Modern dual chamber ICD systems are able to overcome various sensing problems. However, improvement of their performance is still required.

T Wave Oversensing in Implantable Cardioverter Defibrillators
Journal of Interventional Cardiac Electrophysiology, 2004The implantable cardioverter defibrillator is the treatment of choice for patients with ventricular tachycardia, especially in the setting of structural heart disease, but inappropriate therapy continues to be a problem. In this report we describe a short case series of patients who presented with T wave oversensing.

Oversensing of transthoracic excitation stimuli in contemporary pacemakers
Pacing and Clinical Electrophysiology, 2018AbstractBackgroundTransthoracic impedance measurements (TIM) is primarily used for minute ventilation rate adaptive sensors in pacemakers. With elevated impedance, the TIM electrical signal itself is oversensed, causing device malfunction.ObjectiveWe report an increased incidence of TIM oversensing.MethodRetrospective chart review.

Oversensing by Single-Chamber Pacemakers: Mechanisms, Diagnosis, and Treatment
Cardiology Clinics, 1985Signals responsible for pacemaker oversensing may arise from the pacing system itself, P or T wave, concealed ventricular extrasystoles, skeletal muscle potentials, and distant electromagnetic fields. Oversensing is the most common cause of pacemaker pauses and a common clinical problem during follow-up of patients with implanted pulse generators. This

The “Pain wave”: P‑wave oversensing in subcutaneous ICD
Herzschrittmachertherapie + Elektrophysiologie, 2016A 46-year old man was implanted with a totally subcutaneous implantable defibrillator, after having a documented episode of cardiac arrest due to idiopathic ventricular fibrillation. During the 4‑month follow-up, an episode of inappropriate triple counting due to P‑ and T‑wave oversensing was detected.

Atrial Oversensing and Optimizing His Bundle Lead Position
2020His bundle pacing has the advantage of restoring physiologic ventricular activation, rather than mimicking it as is the case with biventricular pacing. Engaging intact His-Purkinje fibers distal to conduction disease reestablishes multisite simultaneous endo-to-epicardial activation, resulting in normal torsional contraction and optimal cardiac output.
