Atrial vectorcardiogram in left atrial rhythm.
The atrial vectorcardiograms of two cases of lefi atrial rhythm are described. The essential vectorcardiographic features of the usual type of this ectopic rhythm, with its variations, are discussed. The probable sites of origin of these variations are considered. It is suggested that the atrial vectorcardiogram amplified to the greatest possible magnification is the best and most direct means ...
متن کاملTemporal sequence of right and left atrial contractions during spontaneous sinus rhythm and paced left atrial rhythm.
The sequence of right and left atrial contractions was analysed in 8 patients during spontaneous sinus rhythm and paced left atrial rhythm. During sinus rhythm, the beginning or peak of the right atrial a wave invariably preceded the beginning or peak of the left atrial a wave by a median of 32 and 34 msec, respectively. During paced left atrial rhythm, the beginning or peak of the right atrial...
متن کاملLeft Atrial, Left Atrial Appendage and Pulmonary Veins Anatomical Variants in Patients with Atrial Fibrillation versus Patients in Sinus Rhythm.
The aim of the study is to evaluate by multidetector computed tomography (MDCT) the prevalence, location and size of LA (left atrial) diverticula and accessory appendages, the prevalence of PVs anatomical variants and LAA (left atrial appendage) shapes in patients with atrial fibrillation (AF) compared to patients in sinus rhythm (SR). Images obtained by MDCT in a group of 100 patients with <1 ...
متن کاملEmbolic stroke, sinus rhythm and left atrial mechanical function.
A 64-year-old man manifested a stroke two years after restoration of sinus rhythm through a radiofrequency catheter ablation. Transesophageal echocardiography demonstrated the presence of a thrombus in the left atrial appendage. Left atrial volumes and different parameters of atrial emptying showed that, despite the persistence of the sinus rhythm, atrial mechanical function was severely impair...
متن کاملRelationship of Left Ventricular Size to Left Atrial and Left Atrial Appendage Size in Sinus Rhythm Patients with Dilated Cardiomyopathy
INTRODUCTION Thromboembolic events are a frequent cause of mortality in patients with congestive heart failure. The aim of or study was to evaluate the relationship of left ventricular end diastolic diameter (LVEDD) to left atrial (LA) size and left atrial appendage (LAA) size in patients with dilated cardiomyopathy in sinus rhythm, as well as to determine the prevalence of thrombi in LV and LA...
