Abstract Two cases of atrial standstill are presented, one with cardiac amyloidosis, the other with idiopathic dilated cardiomyopathy.[ncbi.nlm.nih.gov]
Atrial standstill has been associated with several conditions including, but not restricted to, congenital heart disease, valvular heart disease, conduction disturbances, Brugada syndrome, myocardial infarction, and amyloidosis.[ncbi.nlm.nih.gov]
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.[ncbi.nlm.nih.gov]
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]
Thus, persistence of atrial standstill in asymptomatic cardiomyopathy is a sign of poor prognosis.[ncbi.nlm.nih.gov]
Abstract An asymptomatic patient with cardiomegaly caused by isolated right atrial standstill is reported. The right atrium showed no evidence of contraction on pressure records or angiographically, while the left atrium functioned normally.[ncbi.nlm.nih.gov]
The patient remained asymptomatic after receiving a VVIR pacemaker and anticoagulation therapy.[ncbi.nlm.nih.gov]
Following the implantation of an epicardial ventricular pacemaker, the patient became completely asymptomatic despite the persistence of electrical and mechanical atrial standstill.[ncbi.nlm.nih.gov]
The patient remained asymptomatic after receiving a single chamber implantable cardioverter-defibrillator (ICD) with VVI pacemaker function. KEYWORDS: Atrial standstill; cardiopulmonary resuscitation; dilated cardiomyopathy; sudden cardiac death[ncbi.nlm.nih.gov]
Abstract An asymptomatic patient with cardiomegaly caused by isolated right atrial standstill is reported. The right atrium showed no evidence of contraction on pressure records or angiographically, while the left atrium functioned normally.[ncbi.nlm.nih.gov]
Chest X-ray revealed marked cardiomegaly with right and left chamber enlargement. Echocardiography showed massively dilated right and left atria along with mild tricuspid and mitral regurgitation.[synapse.koreamed.org]
There was mild pulmonary edema, with Kerley's B lines on chest films, without evidence of cardiomegaly.[nejm.org]
Abstract A case of persistent atrial standstill associated with muscular dystrophy of the limb girdle type is reported for the first time in the literature, In spite, of advanced myopathy, the patient delivered an apparently normal child.[ncbi.nlm.nih.gov]
Neither patient had peripheralneuropathy, gastrointestinal disorder, or renal dysfunction. Familial atrial standstill is usually associated with peripheralneuropathy.[ncbi.nlm.nih.gov]
Abstract A 55 year old man with hypertensive cardiovascular disease and uremia was studied. Atrial standstill was confirmed by intracardiac electrocardiography and by inability to stimulate the atria using intraatrial cardiac electrical pacing.[ncbi.nlm.nih.gov]
Patients with atrial standstill were older (P 0.036), had lower diastolic blood pressure (DBP; P CONCLUSIONS: Hyponatremia and decline in DBP are associated with atrial standstill in patients with hyperkalemia. (Circ J 2016; 80: 1781-1786).[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]
The importance of the examination of His bundle electrography in persistent atrial standstill and the diagnostic criteria and treatment of this lesion are discussed.[ncbi.nlm.nih.gov]
In the patient with amyloidosis (ANP: 170 pg/ml, BNP: 1220 pg/ml), a dual chamber pacemaker was successfully implanted for the treatment of sinus arrest. However, loss of atrial capture occurred 1 month later.[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]
The etiology of atrial paralysis in this case remains unknown; the etiopathogenesis of this rare disorder is discussed.[ncbi.nlm.nih.gov]
Abstract Electrophysiologic studies including His bundle recording, atrial, and ventricular stimulation, were performed in three symptomatic patients with persistent atrial standstill of unknown etiology.[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]
However, the main etiology remained unknown as our patient did not give consent for a genetic evaluation. In such patients, implanting a PPM is thought to confer a better life style and symptom reduction. 3 References 2.[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]
