          Abstract

          An electrocardiogram showing atrial flutter in which varying ratios of AV conduction and the cyclical recurrence of varying QRS morphologies are observed is presented.

          Differential diagnosis of wide QRS tachycardia: A review

          Zainul Abedin (2021)
          Differential diagnosis of wide QRS tachycardia (WQRST) on the electrocardiogram remains a challenging exercise. Correct diagnosis is important for prescribing appropriate therapy and determining prognosis. Differential diagnosis of wide QRS tachycardia revolves around differentiation between supraventricular tachycardia with aberrant conduction and ventricular tachycardia. Observations such as clinical history, findings of physical examination during tachycardia, AV dissociation, QRS morphology in lead V1 and lead V6, precordial concordance, RS complexes in precordial leads, contralateral bundle branch block during wide QRS tachycardia, R wave morphologies in lead aVR, and ventricular initial/terminal velocity of conduction ratio can help arrive at the correct diagnosis with reasonable accuracy. The observations described here can help arrive at the correct diagnosis of WQRST with both reasonable accuracy and confidence. The diagnosis of wide QRS tachycardia can be challenging, but is essential for appropriate therapy. The differentiation is often between supraventricular tachycardia with aberrant conduction and ventricular tachycardia. A review of historical, clinical, electrocardiographic information during wide QRS tachycardia while keeping in mind the pitfalls and exceptions, may help arrive at the correct diagnosis with reasonable accuracy and confidence

            Discriminating atrial flutter from atrial fibrillation using a multilevel model of atrioventricular conduction.

            Eberhard Scholz, Florian Kehrle, Stephan Vossel … (2014)
            The discrimination between atrial flutter (AFlu) and atrial fibrillation (AFib) can be made difficult by an irregular ventricular response owing to complex conduction phenomena within the atrioventricular (AV) node, known as multilevel AV block. We tested the hypothesis that a mathematical algorithm might be suitable to discriminate both arrhythmias.
