A brief overview of surgery for atrial fibrillation [PDF]

open access: yes, 2014
The Maze procedure was the first surgical technique developed to ablate, rather than isolate, atrial fibrillation and was first performed clinically in 1987.

Slow Conduction through an Arc of Block: A Basis for Arrhythmia Formation Post-Myocardial Infarction [PDF]

open access: yes, 2017
Introduction The electrophysiologic basis for characteristic rate-dependent, constant-late-coupled (390 + 54 milliseconds) premature ventricular beats (PVBs) present 4–5 days following coronary artery occlusion were examined in 108 anesthetized dogs.

A Technique for Conducting Noninvasive Cardiac Electrophysiology Studies in Conscious Swine

open access: yesJournal of Investigative Surgery, 1997
A noninvasive method was developed in swine for conducting cardiac electrophysiology (EP) studies without the potential confounding effects of sedatives or anesthetics. Following a 1-week conditioning regimen in the EP laboratory, 1-month-old Hanford miniature swine underwent transvenous pacemaker (PM) implantation under isoflurane anesthesia.

Pulmonary vein isolation with the cryoballoon technique in atrial fibrillation treatment: single centre experience

open access: yesTürk Kardiyoloji Derneği Arşivi, 2013
Objectives: Pulmonary vein (PV) isolation with cryothermal energy is a recently introduced technique in patients with atrial fibrillation (AF). It may reduce procedural times and serious complications associated with radiofrequency (RF) ablation.

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

open access: yes, 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 ...

Arrhythmias After Tetralogy of Fallot Repair [PDF]

open access: yes, 2005
Tetralogy of Fallot is the most common cyanotic congenital heart disease, with a good outcome after total surgical correction. In spite of a low perioperative mortality and a good quality of life, late sudden death remains a significant clinical problem,

Cardiovascular changes after administration of aerosolized salbutamol in horses: five cases [PDF]

open access: yes, 2014
Prevention and treatment of intraoperative hypoxemia in horses is difficult and both efficacy and safety of therapeutic maneuvers have to be taken into account.

Reduced Muscular Carnosine in Proximal Myotonic Myopathy—A Pilot 1H‐MRS Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Myotonic dystrophy type 2 (proximal myotonic myopathy, PROMM) is a progressive multisystem disorder with muscular symptoms (proximal weakness, pain, myotonia) and systemic manifestations such as diabetes mellitus, cataracts, and cardiac arrhythmias.

Andersen-Tawil Syndrome [PDF]

open access: yes, 2006
Andersen-Tawil syndrome (ATS) is a rare condition consisting of ventricular arrhythmias, periodic paralysis, and dysmorphic features. In 2001, mutations in KCNJ2, which encodes the α subunit of the potassium channel Kir2.1, were identified in patients ...

Characterization of the in vivo cardiac electrophysiologic effects of high-dose cocaine in closed-chest, anesthetized dogs with normal hearts [PDF]

open access: yes, 2003
OBJECTIVE: To characterize the cardiac electrophysiologic effects of cocaine. METHODS: In 8 dogs (9-13 kg), electrophysiologic parameters and programmed stimulation were undertaken using transvenous catheters at baseline, and after cocaine intravenous ...
