Differentiation of ventricular tachycardia from supraventricular tachycardia with aberration: value of the clinical history. The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two receding years. Systematic analysis of the ECG following diagnostic algorithms based on predefined criteria will improve diagnostic accuracy in determining the etiology of wide complex tachycardias. This can be found either in VT originating in the left posterior wall or during tachycardias using a left posterior accessory AV pathway for AV conduction. In bundle branch blockthere can be an abnormal second upward deflection within the QRS complex. Failure to deliver a shock in a dual-chamber implantable

    Heart ; Lau EW Images in cardiovascular Medicine. A “wide QRS complex” refers to a QRS complex duration ≥ ms. in medicine, the clinical context in which the wide complex tachycardia (WCT) occurs often.
    For this reason, they are referred to as septal Q waves and can be appreciated in the lateral leads I, aVL, V5 and V6.

    Measured in increased QRS amplitude [3]. However, accurate diagnosis is essential for treatment both in the acute phase and in the medium to long term.

    Physical findings that suggest AV dissociation, such as cannon A waves in the jugular venous pulse, variable intensity of S1, or variable arterial pressure unrelated to breathing, point towards a ventricular origin.

    Although the Vereckei algorithm has been shown to be superior to the Brugada criteria in many cases, it is more time-consuming. Pawar; Siddhartha Duttagupta Alberca, J.

    The QRS complex duration is wide (> seconds or 3 small boxes) in every lead.

    Causes of a widened QRS complex include right or left BBB, pacemaker. Wide refers to a QRS complex duration (width) of greater than or equal to.

    are pro-arrhythmic because of their effects on conduction at the cellular level. Class IC drugs may also cause WCT by slowing atrial rate during atrial flutter until AV conduction occurs with a high ventricular rate and wide QRS complex.
    Differential diagnosis between ventricular and supraventricular tachycardia has important therapeutic and prognostic implications, and although data from clinical history and physical examination may suggest a particular origin, it is the lead surface electrocardiogram that usually enables this differentiation.
