This ECG shows a wide QRS complex, tachycardic rhythm that changes morphology and axis within a few beats (see V1 rhythm strip at the bottom). The findings are characteristic of polymorphic (meaning many shapes) ventricular tachycardia, also known as torsades de pointes, which translates in French to “twisting of the spikes.”
