Systematic ED evaluation of tachycardia using QRS width and rhythm regularity guides accurate acute management.
A systematic approach classifying tachycardia by QRS width and rhythm regularity on a 12-lead ECG is crucial for accurate diagnosis and safe management in the emergency department.

May aid ED clinicians in documenting and classifying tachycardias; leaves open prospective validation of the approach.
Patients present to the emergency department with either an ongoing tachycardia or a history suspicious of a tachycardia. Either way, the tachycardia needs to be documented, preferably on a 12-lead electrocardiogram (ECG) for diagnosis and management. If a tachycardiais not documented, a careful history of the palpitations should be taken to see if further monitoring and investigations are required. If a tachycardia is confirmed on an ECG, the clinician needs to classify it according to two variables: (i) regularity of the rhythm; and (ii) QRS width. This will allow a differential diagnosis to be made.

Chin et al. (2015) conducted a review in Tachycardia. Diagnostic and management approach was evaluated. A systematic approach to tachycardia in the emergency department, focusing on QRS width and rhythm regularity, is crucial for accurate diagnosis and appropriate management.
