Typically observed in ECG tracings of wide complex tachycardia such as VT with AV dissociation.</p> <p>Supraventricular and a ventricular impulses coincide to produce a <em>hybrid</em> complex which is different to the VT complex and the native complex (capture beat)</p> <p>The term ‘<em>fusion beat</em>‘ was originally used to define any <a href="https://litfl.com/wp-content/uploads/2018/10/Fusion-Beat-classification-Malinow-Langendorf-1948.jpg">hybrid QRS complex</a> of atria or ventricular origin. Fusion beats (and capture beats) are not ‘<em>diagnostic</em>‘ or ‘<em>pathognomic</em>‘ of VT and can occur in any arrhythmia (including SVT with aberrancy for example)</p>
