Abstract:
We performed electrical catheter ablation (ECA) in a patient who had old myocardial infarction and drug-refractory sustained ventricular tachycardia (VT). ECA using 100J to the earliest activation site and the pace-mapping site failed to prevent the VT. ECA using the same energy to the site at which mid-diastolic potential was recorded during tachycardia could successfully ablate the VT. Therefore the site of energy delivery was important in VT with old myocardial infarction.
