Radiofrequency Ablation for Post Infarction Ventricular Tachycardia [PDF]

, 2004
Radiofrequency ablation has an important role in the management of post infarction ventricular tachycardia. The mapping and ablation of ventricular tachycardia (VT) is complex and technically challenging.

Pacing failure caused by automatic pacing threshold adjustment system

Journal of Arrhythmia, 2017
Ventricular capture management is an automatic pacing threshold adjustment algorithm that automatically measures pacing threshold through detection of the evoked response after a pacing stimulus. Although it is principally designed to save device battery

Characterization of health care utilization in patients receiving implantable cardioverter-defibrillator therapies: An analysis of the managed ventricular pacing trial. [PDF]

, 2017
BACKGROUND: Implantable cardioverter-defibrillators (ICDs) are effective in terminating lethal arrhythmias, but little is known about the degree of health care utilization (HCU) after ICD therapies.

Ultra-High-Frequency ECG in Cardiac Pacing and Cardiac Resynchronization Therapy: From Technical Concept to Clinical Application

Journal of Cardiovascular Development and Disease
Identifying electrical dyssynchrony is crucial for cardiac pacing and cardiac resynchronization therapy (CRT). The ultra-high-frequency electrocardiography (UHF-ECG) technique allows instantaneous dyssynchrony analyses with real-time visualization.

Long-term Effect of Dual-chamber Pacing on Pressure Gradient at Left Ventricular Outflow Tract in Hypertrophic Obstructive Cardiomyopathy

Journal of Arrhythmia, 2011
A 60-year-old man with hypertrophic obstructive cardiomyopathy (HOCM) was implanted dual-chamber ICD for the purpose of both the left ventricular outflow tract (LVOT) gradient reduction by ventricular pacing and the primary prevention of ventricular ...

Restricting excessive cardiac action potential and QT prolongation: a vital role for IKs in human ventricular muscle [PDF]

, 2005
Background - Although pharmacological block of the slow, delayed rectifier potassium current (I-Ks) by chromanol 293B, L-735,821, or HMR-1556 produces little effect on action potential duration (APD) in isolated rabbit and dog ventricular myocytes, the ...

Ventricle Dyssynchrony in Right Ventricle Apex and Right Ventricle Outflow Tract Pacing: Evaluation by Tissue Doppler Imaging

Majalah Kardiologi Indonesia, 2013
Background : Pacemaker lead implantation at right ventricular apex (RVA) or right ventricular outflow tract (RVOT) have different haemodynamic consecuences, due to ventricular dyssynchrony difference. Tissue Dop-pler Imaging (TDI) clearly shown ventricle

Effects of AV delay programming on ventricular resynchronisation: role of radionuclide ventriculography [PDF]

, 2018
Purpose: Optimal atrioventricular delay (AVD) setting for cardiac resynchronisation therapy, i.e. biventricular pacing in patients with heart failure, remains a formidable challenge.
