Background The palpation of the apex beat, one of the most fundamental physical
examinations, provides a clue to left ventricular (LV) dilatation and hypertrophy; however, its …

We analyzed the performance of the electrocardiogram in the diagnosis of left atrial
enlargement in 1000 unselected consecutive patients (585 men and 415 women, mean age …

Aims The aims of this study were to determine the characteristics of the apex beat in the full
left lateral position in healthy adults, and to assess its value in the diagnosis of left …

Objective—To investigate the value of the P-wave area in diagnosing left atrial enlargement
in patients with mitral stenosis. Methods—We measured the P-wave area from lead II of a …

The identification of LA enlargement may have important clinical implications. Previous
correlations of ECG P wave morphologies associated with LA enlargement and …

Left atrial (LA) enlargement by 2-dimensional (2-D) echocardiography predicts adverse
cardiovascular outcomes. Electrocardiographic (ECG) criteria for LA enlargement are based …

Left atrial (LA) enlargement predicts risk of adverse cardiovascular events, including atrial
fibrillation [1], stroke [2] and death [3]. ECG and chest X-ray are the oldest noninvasive …

INTRODUCTION: The 12-lead surface electrocardiogram (ECG) is commonly used as a
noninvasive modality to assess for left atrial enlargement (LAE), but data comparing ECG …

The ECG is widely used as a screening test for left atrial enlargement (LAE). Surprisingly,
the most widely used criterion of LAE, the P-terminal force in lead V 1 (PTF-V 1) has not …

Left atrial (LA) size was estimated from the apical and parasternal (pst) views in 113 patients
(37 with aortic and 23 with mitral valvular lesions, 22 with cardiomyopathies and other heart …
