WebSinus tachycardia is common in cardiac tamponade; while less frequent, atrial or ventricular tachyarrhythmias may occur as well. 2 FIGURE 4. Electrocardiogram demonstrating electrical alternans, in which the height of the QRS complex alternates with each beat due to the heart swinging within the pericardium. WebBidirectional ventricular tachycardia (BiVT) is a rare ventricular tachycardia (VT) where dual QRS morphologies alternate on a beat-to-beat basis. Given its rarity, it is much less well described in the literature compared to other arrhythmias in terms of its typical surface electrocardiogram (ECG) features and mechanisms, as well as defining ...
