Sinus Node Dysfunction

Sinus node dysfunction refers to a number of conditions producing physiologically inappropriate atrial rates. Symptoms may be minimal or include weakness, palpitations, and syncope. Diagnosis is by...

WolffParkinsonWhite WPW syndrome

Wolff–Parkinson–White syndrome (WPW) is a syndrome of pre-excitation of ventricles of the heart due to an accessory pathway known as the bundle of Kent. This accessory pathway is an abno...

For Patients With Atrial Fibrillation, Routine Electrocardiograms Predict Health Risks

Canadian scientists have determined that routine electrocardiogram (ECG) results for patients with atrial fibrillation (AF) - the most common form of irregular heart beat - can help doctors identify t...

Atorvastatin treatment affects atrial ion currents and their tachycardia-induced remodeling in rabbits.

Aims: Atrial fibrillation (AF) leads to electrical atrial remodeling including alterations of various ion channels early after arrhythmia onset. The beneficial effects of statins in AF treatment due t...

Cryoablation and Angiographic Evidence of a Concealed Right Atrial Appendage to Right Ventricle Accessory Pathway in an Infant.

We report a case of successful cryoablation of a concealed accessory pathway from the right atrial appendage to the right ventricle in an infant. A 4-month-old female who had previously undergone succ...

REPORT: Effects of dexamethasone and atorvastatin on atrial sodium current and its early tachycardia-induced electrical remodeling in rabbits.

Purpose: Atrial fibrillation (AF) results in tachycardia-induced ionic remodeling. Pharmacological prevention of tachycardia-induced ionic remodeling not only with "classical" antiarrhythmics but also...

Tachycardia-Induced Cardiomyopathy After Functional Closure of the Foramen Ovale in a Fetus.

Although fetal tachyarrhythmias are relatively rare, they are an important causes of fetal morbidity and mortality. We report a 30-week pregnant woman with fetal tachycardia, fetal hydrops and ascites...

Effects of selective mineralocorticoid receptor antagonism on atrial ion currents and early ionic tachycardia-induced electrical remodelling in rabbits.

Over the past years, the importance of the renin-angiotensin-aldosterone system in atrial fibrillation (AF) pathophysiology has been recognised. Lately, the role of aldosterone in AF pathophysiology a...
