RESUMO

We report a rare case of tachycardia induced cardiomyopathy resulting from nearly incessant dual antegrade response tachycardia. Criteria necessary for sustaining dual antegrade responses are discussed, including: (1) sufficient antegrade dissociation of the AV node; (2) absence of retrograde conduction over each AV nodal pathway following antegrade conduction over its counterpart; (3) difference between fast and slow pathway conduction times exceeding His-Purkinje refractoriness; and (4) critical timing of sinus impulses relative to preceding AV nodal conduction. Both the arrhythmia and cardiomyopathy were successfully treated by slow pathway ablation.

RESUMO

In patients with a persistent left superior vena cava, placement of a permanent transvenous pacing lead for ventricular pacing via the left subclavian vein can be technically challenging. Permanent pacing was achieved in a patient with a persistent left superior vena cava and absent right superior vena cava using a left ventricular vein. Use of an over-the-wire lead system greatly facilitated this procedure.
