Right atrial enlargement (RAE) is clinically significant due to its prevalence in diagnosing supraventricular arrhythmias. Further, early diagnosis using risk factors like RAE may decrease mortality because patients with RAE are at 9x more risk of arrhythmias and other cardiac conditions compared to their healthy counterparts.

Due to its low frequency of occurrence, more common causes of hoarseness should be considered when suspecting left recurrent laryngeal nerve palsy (LRLN).. When considering cardiovocal syndrome, the most common historical cause is a dilated left atrium due to mitral stenosis, but other causes, including pulmonary hypertension, [2] thoracic aortic aneurysms, an enlarged pulmonary artery [3] and ...
Atrial enlargement refers to a condition where the left atrium or right atrium of the heart is larger than would be expected. It can also affect both atria. It can also affect both atria. [ 1 ]
A 12-lead ECG of a woman with Ebstein's anomaly: The ECG shows signs of right atrial enlargement, best seen in V1. Other P waves are broad and tall, these are termed "Himalayan" P waves. Also, a right bundle-branch block pattern and a first-degree atrioventricular block (prolonged PR-interval) due to intra-atrial conduction delay are seen.
A significant number of people with hypertrophic cardiomyopathy do not have any symptoms and will have a normal life expectancy, although they should avoid particularly strenuous activities or competitive athletics. Asymptomatic people should be screened for risk factors for sudden cardiac death.
Tachycardia-induced cardiomyopathy (TIC) is a disease where prolonged tachycardia (a fast heart rate) or arrhythmia (an irregular heart rhythm) causes an impairment of the myocardium (heart muscle), which can result in heart failure.

ECG can show left atrial enlargement, due to increased pressures in the left atrium. [32] Echocardiography is helpful in determining the severity of the disease by estimating the pulmonary artery systolic pressure. [32] This test can also show leaflet calcification and the pressure gradient over the mitral valve. [32]
