Implantable cardioverter-defibrillator Evaluation of clinical neurologic outcome and electroencephalographic changes during implantation

, 1995
During placement of implantable cardioverter-defibrillators, ventricular arrhythmias are induced to test the function of the devices. Although cerebral hypoperfusion and ischemic electroencephalographic changes occur in patients while implantable ...

Left Ventricular wall Thickness and Decrement Evoked Potentials in Ablation of Ischemic Ventricular Tachycardia

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Introduction Preprocedural imaging can improve the success rate of ventricular tachycardia (VT) ablation. Left ventricular wall thickness (LVWT) measured by cardiac computed tomography (CT) can be used to identify infarct regions. We sought to determine whether an association exists between left ventricular wall thickness (LVWT) as obtained ...

Radiation therapy of a patient with implantable cardioverter defibrillator

, 2015
A number of patients who require radiation therapy may suffer from different comorbidities. Cardiac rhythm disturbances represent a comorbidity which in terms may require the implantation of a permanent pacemaker or an implantable cardioverter ...

Safety and Performance of INVICTA DF4 Ventricular Defibrillation Lead: Results From APOLLO Prospective Multicenter Study

Pacing and Clinical Electrophysiology, EarlyView.
Abstract Background Implantable cardioverter‐defibrillator (ICD) therapy relies on reliable right ventricular leads for pacing, sensing, and defibrillation. The INVICTA DF4 lead is an active‐fixation, quadripolar design intended to optimize implant workflow and long‐term safety and performance. Methods APOLLO was a prospective, multicenter, single‐arm,

First Experience With Extravascular Implantable Cardioverter‐Defibrillator Under Deep Sedation

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background The Extravascular Implantable Cardioverter‐Defibrillator (EV‐ICD) utilizes a substernal lead to provide defibrillation and anti‐tachycardia pacing (ATP) while avoiding transvenous complications. General anesthesia (GA) was applied for implantation procedures in the EV‐ICD pivotal trial and is currently recommended by the ...

Repolarization adaptation to rapid change in heart rate in human models – a review

The Journal of Physiology, EarlyView.
Abstract figure legend This review focuses on non‐invasive assessment of repolarization duration and dispersion (heterogeneity) adaptation to change in heart rate (HR). HR was increased incrementally by left atrial pacing during an electrophysiology (EP) study and by a bolus injection of atropine and in a step up/down fashion by repeated right atrial ...

In silico predictions of action potential propagation in doxorubicin cardiotoxicity: A parametric study using preclinical 3D magnetic resonance imaging‐based fibrotic left ventricle models

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of the study's methodology and key findings. In a preclinical swine model, doxorubicin administration induced cardiotoxicity, characterized by diffuse fibrotic remodelling and altered electrical function, as assessed by magnetic resonance (MR) imaging and electrophysiological mapping.

Multicenter Automatic Defibrillator Implantation Trial-Subcutaneous Implantable Cardioverter Defibrillator (MADIT S-ICD): Design and clinical protocol

, 2017
Patients with diabetes mellitus, prior myocardial infarction, older age, and a relatively preserved left ventricular ejection fraction remain at risk for sudden cardiac death that is potentially amenable by the subcutaneous implantable cardioverter ...

Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes

The Journal of Physiology, EarlyView.
Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.
