HeartRhythm Journal CME December 2019: Isolated very low QRS voltage in the frontal leads predicts recurrence of neurally mediated syncope
Description
Journal CME/HeartRhythm Journal
December 2019, Volume 16, Issue 12

The study was prompted by our observation that some patients with neurally mediated syncope (NMS) have an isolated QRS complex, of very low voltage (≤0.3 mV cutoff), in 1 of the frontal leads on the 12-lead electrocardiogram. The objective was to prospectively evaluate whether the presence of isolated very low voltage (VLV) predicts recurrence of NMS.

Learning Objectives

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

1. Recognize the potential importance of the electrocardiogram in the workup for syncope.

2. Identify the presence of very low QRS voltage on electrocardiogram.

3. Relate concepts and knowledge regarding the mechanism of voltage generation on a 12-lead electrocardiogram.

4. Use concepts regarding mechanism of voltage generation during electrocardiogram analysis.

5.  Formulate a hypothesis relating the presence of very low QRS voltage on the 12-lead electrocardiogram and pathogenesis of neurally mediated syncope.

Target Audience
This activity is designed for all professionals who participate in the care and management of heart rhythm disorders.
