Role of electroanatomic mapping in assessing the extent of atrial standstill: diagnostic and therapeutic implications.
Atrial standstill is characterized by failure of atrial excitation, either spontaneous or induced by atrial electric stimulation. We report the case of a 38-year-old man with severe bradycardia and junctional escape rhythm associated with dilative cardiomyopathy. Electroanatomic mapping showed the absence of atrial viability in almost the entire right atrial endocardial surface and excluded the feasibility of atrial pacing.
