A 16-year-old female patient was hospitalized due to narrow QRS tachycardia suggestive of fascicular ventricular tachycardia. Initially, the differential diagnosis with supraventricular tachycardia can be challenging. The tachyarrhythmia is well controlled with medication, but electrophysiological study and ablation may be necessary in patients who remain symptomatic.

In this article, the authors discuss the differential diagnostic methods used in clinical practice to identify types of wide QRS tachycardias (QRS duration >120 ms). A correct diagnosis is critical to management, as misdiagnosis and the administration of drugs usually utilised for supraventricular tachycardia can be harmful for patients with ventricular tachycardia.

This chapter overviews the electrocardiographic diagnosis of various aetiologies of narrow complex tachycardia, as well as the criteria for distinguishing aberrant conduction from ventricular tachycardia in cases of wide QRS tachycardia. Clinical investigations for diagnosis of supraventricular tachycardia are also covered.

Wide Range

Among the most difficult set of arrhythmias to analyze, diagnose, and treat appropriately in the electrophysiology laboratory are wide QRS tachycardias. The reasons for this difficulty include the relatively rare occurrence of some of these conditions and the fact that the differential diagnosis for a wide QRS rhythm includes all the possibilities for a narrow QRS rhythm and, in addition, arrhythmias related to antegrade pathway conduction and ventricular tachycardia. This wide range of possibilities can be confusing even to experienced electrophysiologists, and a complex case may lead to inappropriate diagnoses and maneuvers, including a wrong ablation sequence. This chapter focuses on the overall approach to wide QRS tachycardias. A brief description of the clinical and electrocardiographic features is followed by an in-depth discussion of diagnostic maneuvers and approaches in the electrophysiology laboratory. Finally, representative electrograms and case studies follow to illustrate some of the more involved principles discussed in this chapter.

Qrs Morphology

Verapamil-sensitive fascicular ventricular tachycardia (VT) is the most common form of idiopathic left VT. According to the QRS morphology and the successful ablation site, left fascicular VT can be classified into three subgroups: left posterior fascicular VT, whose QRS morphology shows right bundle branch block (RBBB) configuration and superior axis (common form); left anterior fascicular VT, whose QRS morphology shows RBBB configuration and right-axis deviation (uncommon form), and upper septal fascicular VT, whose QRS morphology shows narrow QRS configuration and normal or right-axis deviation (rare form). Posterior and anterior fascicular VT can be successfully ablated at the posterior or anterior mid-septum with a diastolic Purkinje potential during VT or at the VT exit site with a fused pre-systolic Purkinje potential. Upper septal fascicular VT can also be ablated at the site with diastolic Purkinje potential at the upper septum. Recognition of the heterogeneity of this VT and its unique characteristics should facilitate appropriate diagnosis and therapy.

Pelvic Masses

Pelvic masses can pose a diagnostic dilemma with a broad differential to include both gynecological and non-gynecologic etiologies. While the initial instinct may be to search for gynecologic causes for the female patient, non-gynecologic etiologies must be considered as well. The presentation can be similar amongst many different causes of pelvic masses and imaging is generally required for further assessment to determine if the mass is intra- or extraperitoneal. The etiology of adnexal masses covers several subspecialties: gynecology, urology, gastroenterology, neurology, and oncology. For this reason, it is important for all to be aware of the differential diagnosis for pelvic masses.
