New CME Activities on Supraventricular Tachycardias
In this set of activities, Dr. Nishant Verma reviews the epidemiology, pathophysiology, clinical findings, and management of various types of SVTs, including atrial tachycardia, AV nodal reentrant tachycardia (AVNRT), and accessory pathway-mediated tachycardias. ECG findings for the various SVTs are discussed and compared.

SVT Overview and AVNRT
Description:
In this activity, electrophysiologist Dr. Nishant Verma reviews the mechanisms, epidemiology, and clinical features of supraventricular tachycardias. Electrocardiographic findings of SVT and ways to differentiate SVT from VT are also discussed.
Learning Objectives:
- Compare the mechanisms of the common supraventricular arrhythmias
- Describe the ECG features of SVT
- Describe ECG features that distinguish SVT from VT
- Describe dual AV nodal physiology and the mechanism of re-entry for AVNRT
Accessory Pathway-Mediated Tachycardias
Description:
In this activity, electrophysiologist Dr. Nishant Verma reviews the physiology of accessory pathways and ventricular pre-excitation, including concealed and manifest accessory pathways. He also discusses the mechanism of orthodromic and antidromic AV reentrant tachycardias, including Wolff-Parkinson-White syndrome. Lastly, the management of accessory-mediated tachycardias is reviewed.
Learning Objectives:
- Describe the clinical significance of a delta wave on ECG
- Describe conditions where an accessory pathway may be present despite a normal appearing ECG
- Distinguish orthodromic from antidromic AVRT
- Outline the assessment of asymptomatic and symptomatic patients with a pre-excited pattern on ECG
Atrial Tachycardia
Description:
In this activity, electrophysiologist Dr. Nishant Verma reviews the mechanism, clinical features, and management of atrial tachycardia. He also discusses ECG features and how to differentiate focal and multifocal AT from other types of supraventricular tachycardias.
Learning Objectives:
- Describe the mechanism of focal atrial tachycardia (AT) and multifocal atrial tachycardia (MAT)
- Describe clinical and ECG features that can help distinguish atrial tachycardia from other forms of supraventricular tachycardia (SVT)
- Compare the role of AV node targeted therapy in AVNRT, AVRT, and AT
Principles of SVT Treatment
Description:
In this activity, electrophysiologist Dr. Nishant Verma reviews acute and chronic management of SVT. Vagal maneuvers, pharmacotherapy, and catheter ablation are discussed. Management of SVT in pregnant women is also included.
Learning Objectives:
- Describe vagal maneuvers that can effectively terminate SVT
- Describe the role and risks of using adenosine in patients with SVT
- Recognize indications for EP study and catheter ablation to manage SVT
- Outline special considerations in managing SVT during pregnancy
