Atypical Atrial Flutter: Electrophysiological Characterization and Effective Catheter Ablation

Journal of Cardiovascular Electrophysiology

ABSTRACT Atrial flutter (AFL), defined as macro-re-entrant atrial tachycardia, is associated with debilitating symptoms, stroke, heart failure, and increased mortality. Atypical AFL is a heterogenous group of re-entrant atrial tachycardias that most commonly occur in patients with prior heart surgery or catheter ablation.

Hence, the electrophysiological and ablation target characteristics are poorly described. Focal AT at the aorta-mitral annulus conjunction (AMC) is uncommon.

Transcatheter ablation of atrioventricular nodal reentry tachycardia in children and congenital heart disease in the era of 3D mapping

Frontiers in Cardiovascular Medicine

Atrioventricular nodal reentrant tachycardia (AVNRT) is a common supraventricular tachycardia in children and congenital heart disease (CHD) patients. Nowadays, in large enough children, chronic treatment for symptomatic and recurrent AVNRT episodes relies on transcatheter ablation.

Electrical instability in a healthy 50 year old. How to manage?

Dr. Smith's ECG Blog

During observation in the ED the patient had multiple self-terminating runs of Non-Sustained monomorphic Ventricular Tachycardia (NSVT). The patient has been scheduled for a PVC ablation procedure. This patient very likely has some form of idiopathic ventricular tachycardia. Potassium and magnesium serum levels were normal.
