Right ventricular hypertrophy is the intermediate stage between increased right ventricular pressure (in the early stages) and right ventricle failure (in the later stages). [11] As such, management of right ventricular hypertrophy is about either preventing the development of right ventricular hypertrophy in the first place, or preventing the ...
In either condition fewer than 10% of patients with significant hypertrophy display a normal EKG. [ 15 ] Transthoracic echocardiography , a similarly non-invasive assessment of cardiac morphology, is also important in determining both the degree of hypertrophy, underlying pathologies (such as aortic coarction), and degree of cardiac dysfunction.
Normal heart (left) and right ventricular hypertrophy (right) Investigations available to determine the cause of cor pulmonale include the following: [1] Chest x-ray – right ventricular hypertrophy, right atrial dilatation, prominent pulmonary artery; ECG – right ventricular hypertrophy, dysrhythmia, P pulmonale (characteristic peaked P wave)
Paroxysmal tachycardia is a form of tachycardia which begins and ends in an acute (or paroxysmal) manner. It is also known as Bouveret-Hoffmann syndrome. [ 1 ] [ 2 ] [ 3 ]
Enlargement of right ventricular myocardial mass can result in right axis deviation. There are 2 main reasons for this mechanism. [ 15 ] Firstly, more muscle mass will result in greater amplitude of depolarisation of that side of the heart. [ 15 ]
Congenital abnormalities are much less common than acquired. The most common acquired TR is due to right ventricular dilatation. Such dilatation is most often due left heart failure or pulmonary hypertension. Other causes of right ventricular dilatation include right ventricular infarction, inferior myocardial infarction, and cor pulmonale. [3]
During AVRT, the electrical signal passes in the normal manner from the AV node into the ventricles. Then, the electrical impulse pathologically passes back into the atria via the accessory pathway, causing atrial contraction, and returns to the AV node to complete the reentrant circuit (see figure).
Pressure overload of the right ventricle leads to right ventricular hypertrophy; right image. Pressure overload refers to the pathological state of cardiac muscle in which it has to contract while experiencing an excessive afterload .
