Does Minimizing Ventricular Pacing Reduce the Incidence of Atrial Fibrillation? A Systematic Review and Meta-analysis of Randomized Controlled Trials

open access: yesCardiovascular Innovations and Applications, 2020
Background: Right ventricular pacing disrupts atrioventricular synchrony and increases the risk of atrial fibrillation (AF). However, whether algorithms for minimizing ventricular pacing reduce the incidence of AF remains controversial.

A novel approach for the diagnosis of ventricular tachycardia based on phase space reconstruction of ECG [PDF]

open access: yesInternational Journal of Cardiology, Volume 172, Issue 1, March 2014, Pages e31-e33, 2014
Ventricular arrhythmias comprise a group of disorders which manifest clinically in a variety of ways from ventricular premature beats (VPB) and no sustained ventricular tachycardia (in healthy subjects) to sudden cardiac death due to ventricular tachyarrhythmia in patients with and/or without structural heart disease.

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

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

Cardiac Memory-induced T-wave Inversions [PDF]

open access: yes, 2020
Introduction: Cardiac memory refers to T-wave inversions that result when normal ventricular activation resumes following a period of abnormal ventricular activation.Case Report: We present a case of a 29-year-old man with a pacemaker who presented with ...

Effect of His Bundle Pacing on Abnormal Myocardial Fatty Acid and Glucose Metabolism Induced by Right Ventricular Pacing

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Metabolic disorder is noted for pacing‐induced cardiomyopathy. The benefits of His bundle pacing over right ventricular (RV) pacing in preventing pacing‐induced cardiomyopathy from a metabolic perspective are yet to be fully understood. Method

Why Pacing Frequency Affects the Production of Early Afterdepolarizations in Cardiomyocytes: An Explanation Revealed by Slow/Fast Analysis of a Minimal Model [PDF]

open access: yesPhys. Rev. E 99, 052205 (2019), 2019
Early afterdepolarizations (EADs) are pathological voltage oscillations in cardiomyocytes that have been observed in response to a number of pharmacological agents and disease conditions. EADs are small voltage fluctuations that occur during the plateau of an action potential.

Higher ventricular rate during atrial fibrillation relates to increased cerebral hypoperfusions and hypertensive events [PDF]

open access: yesScientific Reports, 9: 3779, 2019, 2019
Atrial fibrillation (AF) is associated with cognitive impairment/dementia, independently of clinical cerebrovascular events (stroke/TIA). One of the plausible mechanisms is the occurrence of AF-induced transient critical hemodynamic events; however, it is presently unknown, if ventricular response rate during AF may impact on cerebral hemodynamics.

Changing QRS Morphology: What is the mechanism? [PDF]

open access: yes, 2006
ECG in sinus rhythm with ventricular preexcitation and changing QRS morphology was seen that was initially interpreted as the multiple accessory pathway from elsewhere. (Figure 1A).
