Noninvasive assessment of pulmonary hypertension using continuous-wave Doppler of tricuspid regurgitation can predict morbidity and mortality in patients with ischemic or idiopathic dilated cardiomyopathy.

LVH produces multiple electrophysiological abnormalities and increased vulnerability to inducible polymorphic ventricular arrhythmia in this model of LVH. Cats that show regression of hyperthrophy have normal ventricular electrophysiology and have the same low vulnerability to inducible ventricular arrhythmia as Sham animals.
