Electrophysiological Effects of the Class Ic Antiarrhythmic Drug Pilsicainide on the Guinea-Pig Pulmonary Vein Myocardium

open access: yesJournal of Pharmacological Sciences, 2012
The pulmonary vein is known as an important source of ectopic beats, initiating frequent paroxysms of atrial fibrillation. We compared effects of the class Ic antiarrhythmic drug pilsicainide on the electrophysiological parameters in the isolated ...

Evidence that conflict regarding size of haemodynamic response to interventricular delay optimization of cardiac resynchronization therapy may arise from differences in how atrioventricular delay is kept constant. [PDF]

open access: yes, 2014
Aims: Whether adjusting interventricular (VV) delay changes haemodynamic efficacy of cardiac resynchronization therapy (CRT) is controversial, with conflicting results.

Asymptomatic Giant Left Atrium [PDF]

open access: yesClinical Cardiology, 2010
AbstractGiant left atria (GLA) is a condition where the left atrial diameter exceeds 65 mm.1 It is closely related to rheumatic mitral valve regurgitation or mixed mitral disease with predominant regurgitation and tends not to occur in patients with mitral regurgitation due to other causes.2 The majority of patients are symptomatic with the most common

Living without left atrium [PDF]

open access: yesBMJ Case Reports, 2013
A 51-year-old female patient presented to the emergency room with a 3-month history of increasing dyspnoea, and 5 kg weight loss. Her medical history was not relevant. Physical examination revealed 100/90 mm Hg blood pressure, 98 bpm, orthostatic hypotension, a soft grade 2/6 systolic murmur at the left sternal border and bilaterally pulmonary rates ...

The Impact of Left Atrium Appendage Morphology on Stroke Risk Assessment in Atrial Fibrillation: A Computational Fluid Dynamics Study

open access: yesFrontiers in Physiology, 2019
Atrial fibrillation (AF) carries out a 5-fold increase in stroke risk, related to embolization of thrombi clotting in left atrium (LA). Left atrial appendage (LAA) is the site with the highest blood stasis which causes thrombus formation.
