An atrial septal defect (ASD) is a hole in the heart between the upper chambers (atria). . Am J Cardiol. In this case, the amount of enlargement in the left atrium can reveal the level of dysfunction of the left ventricle. The ECG criteria for atrial abnormality are highly specific but insensitive when compared with cardiac magnetic resonance imaging (MRI). A large atrial septal defect can cause extra blood to overfill the lungs and overwork the right side of the heart. Left atrial abnormality is suggested by P wave duration 120 milliseconds or greater, widely notched P wave 40 milliseconds or . Atrial fibrillation (AF) is associated with an increased risk of ischemic stroke, heart failure, cognitive decline, dementia, myocardial infarction, sudden cardiac death (SCD), and all-cause death.

The electrical measurements on the electrocardiogram can often mislead physicians in diagnosing the heart condition left ventricular hypertrophy, causing other screening tests to be ordered before a definitive conclusion can be made, according to a Henry Ford Hospital study. Left ventricular hypertrophy was confirmed by echocardiographic determination of left ventricular (LV) mass in both groups. These are expressed in the electrocardiogram (ECG) by the presence of a P wave duration that equals or exceeds 120 milliseconds and presents usually a bimodal morphology . The most common cause of heart failure occurs when the heart is weak and enlarged. Phleboliths are also called vein stones and are relatively common.
