ABSTRACT
An 80-year-old man underwent catheter ablation for atrial tachycardia
(AT), which developed after catheter ablation for atrial fibrillation.
The AT was diagnosed as dual-loop tachycardia, which included
peri-mitral and roof-dependent ATs. An ethanol infusion into the vein of
Marshall resulted in left phrenic nerve paralysis. During the procedure,
the phrenic nerve paralysis was completely relieved.
