In a case report published in 1984 in the New England Journal of Medicine, Figure 1 was an electrocardiogram that showed sinus bradycardia with a short PR interval and prominent delta waves, with a pattern of preexcitation typical of a posteroseptal accessory pathway (PSAP).1

Chronic recurrent monomorphic VT like fascicular tachycardia and right ventricular outflow tract tachycardia are also amenable to electrophysiological mapping and ablation. Recurrent ventricular tachycardia in spite of radiofrequency catheter ablation needs an implantable cardioverter defibrillator.

Abstract Introduction Severe transitory episodes of bradycardia with subsequent syncope in children are common, and generally portend a benign prognosis. Rarely, patients may experience prolonged asystolic episodes secondary to significant sinus pauses (SP) or paroxysmal atrioventricular block (AVB).

Ablation to prevent recurrent flutter was performed. These include not only induction of significant bradycardia ( albeit usually short-lived ) — but also both ventricular and supraventricular tachyarrhythmias. The subsequent EP study could not induce VT, only atrial fibrillation.

3] So a patient with WPW can have the pattern induced by ischemia, and there is also a report of a patient with pre-existing WPW which was “ablated” by myocardial infarction after an LAD occlusion.[4] Delta waves are seen in 11/12 leads. In most of these leads — the PR interval is clearly shortened, with resultant QRS widening.

There was no evidence bradycardia leading up to the runs of PMVT ( as tends to occur with Torsades ). If there had been — a temporary atrial pacemaker could have been considered as a way of increasing the heart rate to suppress a bradycardia-dependent arrhythmia ("overdrive pacing").

This ECG shows sinus bradycardia with massively long QT (or QU?) Especially when present in the setting of bradycardia and syncopal episodes, this is very worrisome for high risk of lethal dysrhythmias including polymorphic ventricular fibrillation (termed Torsades when in the setting of long QT). interval, at over 600 msec.

There are 2 main options: Overdrive pacing could be considered and in the right clinical situation, this is often effective for reducing ventricular arrhythmias ( especially in the case of preventing pause induced or bradycardia-induced arrhythmias in association with QTc prolongation ). Try a different kind of antiarrhythmic.
