other causes of isolated right ventricular failure. Treatment effected good control of clinical signs, until acutely decompensated congestive right heart failure led to euthanasia after 4 months. Arrhythmogenic right ventricular cardiomyopathy is a well-described clinical entity in humans, and has previously been documented in 3 male dogs.

Right Ventricular Hypertrophy For determining the presence or absence of right ventricular hypertrophy (RVH), use only lead V1. The 4-step method has 3 rules for RVH: 1. Upright T waves in V1 after about 7 days of age (Figure 29).3 The T waves in V1 are inverted after 7 …

Right ventricular hypertrophy in agroup ofcoalworkers The main source of the material was the pneumoconiosis medical panels and thus subjects were somewhat biased towards those with estab- lished disease. Nevertheless, somesubjects with no radiographic evidence of coalworkers' pneumo-
The role of right ventricular hypertrophy in the patho genesis of right ventricular infarction remains controversial (3,15-17). Animal models support the role of increased right ventricular afterload and hypertrophy in the pathogen esis of right ventricular infarction (18). However, most clin
Right Ventricular Hypertrophy: A New "Risk Factor" for Right Ventricular Infarction?* NORMAN KRASNOW, MD Brooklyn . New York The right ventricle is a somewhat strange organ; it seems to function as a pump quite well even when its wall is deliberatelydestroyedby a cauteryor whenitsbloodsupply is severely compromised. Infarction of the right ...
Right ventricular infarctionâ diagnosis and treatment
right ventricular dysfunction after MI have spontaneous re- covery of right ventricular function, leading some clinicians26 to believe that the term “right ventricular infarction” is a mis- nomer and represents viable but “stunned” myocardium. The following review gives an insight into the various diagnostic modalities and treatment of RVI.
4. Right ventricular hypertrophy Pathophysiology: The figure below compares the normal anatomy and blood flow of the heart to that found in Tetralogy of Fallot. The initial defect in TOF is a narrowing of the right ventricular outflow tract into the pulmonary artery.

vated afterload on the fetal right ventricle, as in the case of premature constriction of the ductus arteriosus or the recipient twin-to-twin transfusion syndrome. Rarely, isolated RVH may present in fetal life, in the setting of Noonan’s syndrome.1 Premature closure of the ductus arteriosus is a rare cause of isolated RVH. This was the
