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.

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.

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.

Embolization from the Atria in Arteriosclerotic Heart Disease
JAMA, 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%).

Specialized tissues and preferential conduction in the atria of the heart
The American Journal of Cardiology, 1971Abstract Many of the widely prevalent concepts in clinical electrocardiography are based on the premise that the spread of electrical activity in the atria is radial, not following special pathways. This review questions that premise on the grounds of recent electrophysiologic, biochemical and anatomic studies that are more logically interpreted as ...
