HeartRhythm Journal CME September 2019: Clinical and electrophysiological characteristics of idiopathic ventricular arrhythmias originating from the slow pathway region
Journal CME/HeartRhythm Journal 
September 2019, Volume 16, Issue 9 

The slow pathway region (SPR) is commonly targeted during ablation of atrioventricular nodal reentrant tachycardia. However, its role in idiopathic ventricular arrhythmias (IVAs) remains unknown. The objective of this article is to describe the ECG and electrophysiological characteristics of IVAs that were successfully ablated from the SPR.

Learning Objectives

Upon completion of this activity, participants will be able to:

  • Recognize the electrocardiographic and electrophysiological characteristics of idiopathic ventricular arrhythmias that were successfully ablated from the slow pathway region.
  • Identify the anatomical features of the slow pathway region and its proximity to the infero-basal left ventricle.
  • Understand the appropriate technique for safely and effectively ablating ventricular arrhythmias originating from this location.
  • Demonstrate understanding of localization of ventricular arrhythmias from the slow pathway region for appropriate procedural planning and patient counseling.
Target Audience
This activity is designed for all professionals who participate in the care and management of heart rhythm disorders.
