Abstract:
Atrial standstill is a rare form of bradyarrhythmia and consists of a transitory or permanent loss of the electrical and mechanical activity of the atria. It has been described in a few cases of long-standing valvular disease, amyloidosis, myocarditis, and muscular dystrophy. We report on a young female with noncompaction cardiomyopathy that progressed to congestive heart failure. Electrocardiogram showed persistence atrial standstill that was confirmed clinically and by electrocardiomyopathy, Doppler two-dimensional echocardiogram, and tissue Doppler imaging. We assume that worsening of asymptomatic noncompaction and progression to the congestive form of cardiomyopathy could be presaged by the presence of persistent atrial standstill. Thus, persistence of atrial standstill in asymptomatic cardiomyopathy is a sign of poor prognosis.

Cardiac Action Potential
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.
