Isolated idiopathic right ventricular dilated cardiomyopathy

Right ventricular dilated cardiomyopathy.

Fourteen patients with predominantly right sided dilated cardiomyopathy were studied, of whom five died suddenly. The condition is characterised by male preponderance, syncope, ventricular tachycardia, which typically has a left bundle branch block pattern on the surface electrocardiogram, and right heart failure. The diagnosis should be considered in patients presenting with otherwise unexplai...

Familial right ventricular dilated cardiomyopathy.

Cardiomyopathy of unknown cause occurred in three of six siblings. The course of the illness was marked by life threatening supraventricular and ventricular arrhythmias, sinoatrial block, atrioventricular block, and embolism (in one patient). The disease was characterised by right ventricular dilatation. Two of the three patients died aged 32 and 48. No new cases of the disease were found when ...

Isolated Right Ventricular Dilated Cardiomyopathy: An Early Diagnosis

Because of an incomplete right bundle branch block, a severe right ventricular dilatation with no left ventricular cardiomyopathy was found in a 44-year-old man. Magnetic resonance and transesophageal echocardiography confirmed the finding and these tests also failed to find any potential cause. A pulmonary hemodynamic study and a coronary angiography were strictly normal. Lastly pulmonary func...

Ventricular arrhythmias in idiopathic dilated cardiomyopathy.

Twenty four hour ambulatory electrocardiograms were recorded in 60 patients with idiopathic dilated cardiomyopathy. The diagnosis was based on clinical, laboratory, and cardiac catheterisation findings. All patients had a left ventricular ejection fraction less than 0.55; in 39 it was less than 0.40. Ventricular extrasystoles were evident in all patients: they were rare in 11 (18%), moderately ...
