Why the study?
Differential diagnosis of wide QRS complex arrhythmias remains difficult in routine practice because electrophysiological examinations carry complications and require specialized equipment, while current ECG criteria often lack accuracy and are complex to apply.

Review
ECG algorithms for wide QRS differentiation may aid bedside assessment; leaves open need for prospective validation against EP study.
Differential diagnosis of ventricular and supraventricular wide QRS complexes arrhythmias remains one of the most urgent and serious problems of modern cardiology. High-precision intracardiac and transesophageal electrophysiological examination cannot be widely used in routine clinical practice because of the complexity of using, the risk of complications, and the necessary of special equipment. The availability and simplicity of electrocardiogram registration was the reason for study and development of ECG criteria and algorithms for differential diagnosis. However, their low accuracy, variety, complexity and laboriousness of application often leads to diagnostic errors and low usage of clinicians.
