Abnormalities of cardiac conduction in diabetics.

Cardiac conduction abnormalities during percutaneous balloon mitral or aortic valvotomy.

To evaluate the electrophysiologic changes in the cardiac conduction system that occur during percutaneous mitral or aortic balloon valvotomy, we prospectively studied the conduction system in 19 patients (10 mitral, 8 aortic, and 1 both) undergoing this procedure. A His bundle electrogram was recorded in all patients, and when sinus rhythm was present, the atrioventricular (AV) node effective ...

Subclinical left ventricular abnormalities in young diabetics.

Twenty young asymptomatic diabetic patients were evaluated for left ventricular dysfunction by determining the radionuclide ejection fraction response to supine bicycle ergometry. The double product at peak exercise (28,743 +/- 3,314 vs 29,007 +/- 3,625, p greater than .05) was not significantly different between the two groups. Seven of 20 diabetics had either no change or a drop in their ejec...

Cardiac conduction system abnormalities in ankylosing spondylitis: a cross-sectional study

BACKGROUND Cardiac conduction disturbances are common in spondyloarthropathies such as ankylosing spondylitis (AS). Whether their occurrence can be linked to signs and symptoms of rheumatic disease activity is an unsettled issue addressed in this study. METHODS In this cross-sectional study patients with AS according to modified New York criteria but without psoriasis, inflammatory bowel dise...
