a. The goal of the EP study is either sustained or non-sustained ventricular tachycardia
b. Patients with less than 5 repetitive complexes in response to stimulation are considered noninducible
For arrhythmias of ventricular origin, the EP study goal is either sustained or nonsustained ventricular tachycardia. Patients with less than five repetitive complexes in response to stimulation are considered noninducible. Ventricular reentry does not occur in normal myocardium, so all reentrant arrhythmias are pathological. Macroreentry arrhythmias are typical after myocardial infarction, while microreentry arrhythmias are typical of myocardial ischemia.
