Embolization from the Atria in Arteriosclerotic Heart Disease
JAMA - Journal of the American Medical Association, 1961One thousand autopsied cases were studied to determine the incidence of embolism from the atria in arteriosclerotic heart disease. In this study, it was found that 1 case of embolization occurred in a total of 52 patients with atrial fibrillation (2%), and 2 cases of embolization occurred in a total of 243 cases who were nonfibrillators (0.8%).

Neuronal control of heart rate in isolated mouse atria
American Journal of Physiology - Heart and Circulatory Physiology, 2003A novel mouse isolated atrial preparation with intact postganglionic autonomic innervation was used to investigate the neuronal control of heart rate. To establish whether autonomic activation was likely to alter heart rate by modulating the hyperpolarization-activated current ( If), the L-type Ca2+current ( ICa,L), or the ACh-activated K+current ( IK ...

Depolarization of the Rat Atria in Experimental Simulation of the Holiday Heart Syndrome
Doklady Biochemistry and Biophysics, 2020In the study of the sequence of depolarization of the atrial subepicardium of rats in the short-term alcohol consumption model (the "Holiday heart" syndrome), the localization of the sources of atrial arrhythmias was determined for the first time. The difference in the excitation of the right and left atria was discovered: the right atrium is activated

Circulation, 2015
A 72-year-old woman was admitted to our department for further investigation of a heart defect noted in transthoracic echocardiography performed in a district hospital. The patient complained of palpitations and moderately limited physical activity. On ECG, atrial fibrillation was recorded with a well-controlled ventricular rate.

Primary extramedullary plasmacytoma in the atria of the heart
Cardiovascular Pathology, 2001A rare case of primary extramedullary plasmacytoma of the heart is described. The large space-occupying tumor in the atrial wall and its associated significant pericardial effusion caused marked impairment of cardiovascular function. The diagnosis was made via intravenous biopsy.

The role of the atria in congenital heart disease
Cardiology Clinics, 2002The atria play an important role in adult congenital heart disease. Atrial function is often altered due to longstanding pressure or volume overload. Cardiac surgery inflicts lasting damage to the atria, which leads to loss of atrial compliance. Both the history of atrial overload and the atrial scarring form substrates for atrial tachycardias.
