Biventricular hypertrophy ECG. In case the ECG or other examinations suggest left ventricular hypertrophy (LVH), one should suspect concomitant right ventricular hypertrophy (RVH) if the following ECG criteria are presented: Right axis deviation (>90°) – This never occurs in LVH. Deep S-wave in V5 or V6 (>6 mm)

Left atrial enlargement affects people with: High blood pressure. Mitral valve disease. Aortic valve disease. Coronary artery disease. Certain kinds of cardiomyopathy. Diastolic dysfunction. Left ventricular hypertrophy. Congenital heart disease.

Ventricular fibrillation. This type of arrhythmia occurs when rapid, chaotic electrical signals cause the lower heart chambers (ventricles) to quiver instead of contacting in a coordinated way that pumps blood to the rest of the body. This serious problem can lead to death if a normal heart rhythm isn't restored within minutes.

One major difference between re-entrant and non– re-entrant ventricular tachycardia (VT) is that the electrophysiological substrate for re-entry is acquired during postnatal development and is due to anatomic insult (eg, ischemic heart disease or viral myocarditis), whereas the substrate for triggered activity is likely often acquired during.

Problems with the structure or function of your heart that can cause right ventricular hypertrophy include: atrial septal defect (a hole in the wall between your heart’s upper chambers) pulmonary valve stenosis tricuspid valve regurgitation tetralogy of Fallot ventricular septal defect (a hole in.
