R-wave amplitude and left ventricular volume: changes with nitroglycerine and atrial pacing.

The relationship between R-wave amplitude and left ventricular volume was examined using two groups of patients, undergoing diagnostic cardiac catheterisation for investigation of chest pain, who had simultaneous R-wave recording and left ventricular angiography. R-wave amplitude was measured in leads 1, 2, 3 and V4-6. Left ventricular volume was altered by nitroglycerine (n = 18) and atrial pacing (n = 13). In both groups, increase or decrease in left ventricular volume was associated with a concomitant change of R-wave amplitude. We conclude that left ventricular volume is an important determinant of surface-recorded R waves with increased amplitude reflecting increased left ventricular volume and vice versa.

Mycotic aneurysm of the pulmonary artery. Direct surgical approach with preservation of lung tissue.

A solitary mycotic aneurysm of the right apical lower segmental pulmonary artery developed in an 8 year old child with infective endocarditis, ventricular septal defect and pulmonary hypertension. Surgical treatment was undertaken to prevent rupture and achieved by direct ligation of the feeding vessel and endoaneurysmorrhaphy with preservation of all lung tissue. Successful surgical treatment has been described in eight previous cases of mycotic pulmonary artery aneurysm though in only one adult patient has lung resection been avoided.
