Triggered activity as the proposed mechanism of left atrial tachycardia induced by premature ventricular beats

In a 57-year-old woman with complex ventricular ectopy, a paroxysmal supraventricular tachycardia initiated by premature ventricular beats is presented. She underwent an electrophysiologic study. The tachycardia origin was localised to the left atrium. At the presence of retrograde dual atrioventric...
