2. Right atrial enlargement - Wikipedia

   en.wikipedia.org/wiki/Right_atrial_enlargement

   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.

3. Ebstein's anomaly - Wikipedia

   en.wikipedia.org/wiki/Ebstein's_anomaly

   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.

4. P wave (electrocardiography) - Wikipedia

   en.wikipedia.org/wiki/P_wave_(electrocardiography)

   Peaked P waves (> 0.25 mV) suggest right atrial enlargement, cor pulmonale, (P pulmonale rhythm), [1] but have a low predictive value (~20%). [2] A P wave with increased amplitude can indicate hypokalemia. [3] It can also indicate right atrial enlargement. [4] A P wave with decreased amplitude can indicate hyperkalemia. [5]

5. Atrial enlargement - Wikipedia

   en.wikipedia.org/wiki/Atrial_enlargement

   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 ]

6. Right ventricular hypertrophy - Wikipedia

   en.wikipedia.org/wiki/Right_ventricular_hypertrophy

   The right ventricle is one of the four chambers of the heart. It is located towards the right lower chamber of the heart and it receives deoxygenated blood from the right upper chamber (right atrium) and pumps blood into the lungs. Since RVH is an enlargement of muscle it arises when the muscle is required to work harder.

7. Cardiomegaly - Wikipedia

   en.wikipedia.org/wiki/Cardiomegaly

   In this condition, the walls of the left and/or right ventricles of the heart become thin and stretched. [29] In the other types, the heart's left ventricle becomes abnormally thick. Hypertrophy is usually what causes left ventricular enlargement. Hypertrophic cardiomyopathy is typically an inherited condition. [30]

8. Tachycardia-induced cardiomyopathy - Wikipedia

   en.wikipedia.org/wiki/Tachycardia-induced_cardio...

   There are no formal diagnostic criteria for TIC. Thus, TIC is typically diagnosed when (1) tests have excluded other causes of cardiomyopathy and (2) there is improvement in myocardial function after treatment of the tachycardia or arrhythmia. [1] [5] [6] Treatment of TIC can involve treating the heart failure as well as the tachycardia or ...

9. Right axis deviation - Wikipedia

   en.wikipedia.org/wiki/Right_axis_deviation

   This would lead to right axis deviation findings on an ECG. [6] Bifascicular block is a combination of right bundle branch block and either left anterior fascicular block or left posterior fascicular block. Conduction to the ventricle would therefore be via the remaining fascicle.
