Single-chamber Versus Dual-chamber Implantable Cardioverter Defibrillators: Do We Need Physiologic Pacing in The Course? [PDF]

, 2006
Background: Many patients with ICD receive different antiarrhythmic drugs (e.g. sotalol, amiodarone, β-blockers) because of ventricular or atrial tachycardias.

Magnetic Resonance Imaging in patients with ICDs and Pacemakers [PDF]

, 2005
Magnetic resonance (MR) imaging has unparalleled soft-tissue imaging capabilities. The presence of devices such as pacemakers and implantable cardioverter/defibrillators (ICDs), however, is historically considered a contraindication to MR imaging.

Intermittently “Pre-Excited” ECG after Accessory Pathway Ablation: Unsuccessful Procedure or a Complication?

Case Reports in Cardiology, 2012
A 52-year-old woman with previously unsuccessful posteroseptal pathway ablation using radiofrequency energy presented with intermittently occurring short PR followed by a wide QRS complex, and complaining of palpitations with characteristics different ...

Spatiotemporal dynamics of pacing in models of anatomical reentry [PDF]

arXiv, 2001
Reentry around non-conducting ventricular scar tissue, which often causes lethal arrhythmias, is typically treated by rapid stimulation from an implantable defibrillator. However, the mechanisms of termination (success and failure) are poorly understood.

Diastolic And Systolic Right Ventricular Dysfunction Precedes Left Ventricular Dysfunction In Patients Paced From Right Ventricular Apex [PDF]

, 2006
Background: Cardiac dysfunction after right ventricular (RV) apical pacing is well known but its extent, time frame of appearance and individual effect on left ventricular (LV), RV systolic and diastolic parameters has not evaluated in a systematic ...

Cardiac resynchronization therapy in heart failure – Beyond the standard

IHJ Cardiovascular Case Reports, 2017
Cardiac resynchronization therapy device (CRT- defibrillator and CRT-pacemaker) implantations have increased remarkably over the last decade. Conventionally these devices are used in patients with symptomatic systolic left ventricular (LV) dysfunction ...

Prognostic significance of accelerated ventricular response during radiofrequency ablation of premature ventricular complexes

Indian Pacing and Electrophysiology Journal, 2020
Background: Accelerated ventricular response is frequently observed during radiofrequency ablation (RFA) of premature ventricular complexes (PVCs). We hypothesized that acceleration indicates an appropriate site and adequate injury to the arrhythmogenic ...

Risk Stratification for Sudden Cardiac Death In Patients With Non-ischemic Dilated Cardiomyopathy [PDF]

, 2005
Non ischemic dilated cardiomyopathy (NIDCM) is a disorder of myocardium. It has varying etiologies. Albeit the varying etiologies of this heart muscle disorder, it presents with symptoms of heart failure, and rarely as sudden cardiac death (SCD ...

DNA methylation-based telomere length is more strongly associated with long-term all-cause mortality than quantitative polymerase chain reaction-based telomere length among middle-aged and older hypertensive adults

Clinical Epigenetics
Background Telomere length (TL) has been linked to mortality risk across various populations. However, its predictive value for mortality risk specifically in hypertensive adults remains unclear. Methods This cohort study utilized data from the 1999–2000

How to diagnose and manage patients with cardiac implantable electronic device infections

Journal of Arrhythmia, 2013
Over the last two decades, there has been a surge in the number of Cardiac Implantable Electronic Device (CIED) implantation. These devices improve the quality of life and survival among certain cardiac patients.
