In patients with congenital heart disease presenting with bradyarrhythmia, many electrophysiological abnormalities are found. [ncbi.nlm.nih.gov]

A total of 778 patients with hyperkalemia were identified, 28 of whom had atrial standstill, and had several parameters measured prior to any treatment of hyperkalemia. [ncbi.nlm.nih.gov]

Thus, persistence of atrial standstill in asymptomatic cardiomyopathy is a sign of poor prognosis. [ncbi.nlm.nih.gov]

Symptomatic cases require ventricular pacing and treatment for congestive heart failure if present, however, the prognosis is poor. [synapse.koreamed.org]

Etiologies described in the literature have included muscular dystrophy, familial amyloidosis, and rarely myocarditis. These etiologies usually lead to permanent atrial standstill and require ventricular pacing. [ncbi.nlm.nih.gov]

Electrolyte disturbances, vasovagal reflexes from the upper part of the gastrointestinal tract, and hypoxia have all been implicated as temporary etiological factors. [jamanetwork.com]

Abstract Persistent atrial standstill is a very rare pathophysiologic condition whose diagnosis is established when both electrical and mechanical silence of the atria are confirmed. [ncbi.nlm.nih.gov]

Pathophysiological hypotheses of atrial standstill, based on post-mortem examinations, include fibroelastosis and fatty infiltration of the atrial wall [10]. [cardiovascmed.ch]

There are few reports on the pathophysiology of atrial standstill. [academic.oup.com]

Partial atrial standstill may be present and prevent atrial lead implantation in patients with sinus node disease. [ncbi.nlm.nih.gov]

Fibrosis prevents proper conduction and so ventricular contraction occurs in the form of escape beats, and thus the heart rate is slow. ECG examination usually reveals an absence of P waves and may show a widening of the QRS complex. [cal.vet.upenn.edu]

Hemodynamic collapse was prevented by pacing from the coronary sinus ( Figure 2d ). [innovationsincrm.com]
