G.M. Solovyan, Т.V. Mikhalieva Wide QRS complex tachycardia: differential diagnosis and emergency therapy

The lecture is devoted to a serious problem in clinical practice – diagnosis and treatment of wide QRS complex tachycardia, requiring an individual approach. The main principles of the detection of different types of wide QRS complex tachycardia and their electrophysiological mechanisms are considered. The article deals with etiology of wide QRS complex tachycardia, as well as clinical and electrocardiographic criteria for differential diagnosis between ventricular tachycardia and supraventricular tachycardia with aberrant conduction. Key aspects of wide QRS complex tachycardia are discussed, and the ECG examples of certain forms of wide QRS complex tachycardia are presented. The principles of emergency care and long-term therapy for narrow and wide QRS complex tachycardia are considered. Information regarding antiarrhythmic drugs usage and general principles of catheter treatment of tachycardia is provided.
