we conclude that ice mapping can physiologically localize a site responsible for maintenance of ventricular tachycardia by termination of the arrhythmia , and that the presence of bridging or late diastolic electrical activity , slow conduction with cooling-induced block , and absence of spontaneous or triggered automaticity or delayed afterdepolarizations suggest that local cooling terminates ventricular tachycardia by slowing or blocking conduction in a reentrant loop .
