Every couple of years we come across a new published algorithm or decision tools that attempt to once-and-for-all reliably distinguish between VT and SVT-AC. The most recent such attempt, the Basel ...

This ECG (Figure 1), recorded in the emergency room, shows a wide complex tachycardia at 205 bpm. Wide complex tachycardias are more likely to be ventricular tachycardia (VT) than supraventricular ...

This ECG is challenging. The rhythm starts as normal sinus rhythm with a right bundle branch block, then a wide-complex tachycardia develops in a left bundle branch block pattern. The important thing ...

This ECG has a narrow QRS complex initally, then a fast heart rate, regular rhythm and no identifiable P wave activity which suddenly turns to a wide complex in a left bundle branch block pattern. The ...
