[Atrial standstill and rheumatic mitral valvulopathy].

Atrial standstill is a very rare form of bradyarrhythmia and consists of a transitory or permanent loss of the electrical and mechanical activity of the atria. We report a series of 8 patients, all of them with rheumatic valve disease (5 of them with a prosthetic valve) with symptomatic bradyarrhythmia secondary to atrial standstill, requiring an implantable pacemaker.
