Q waves and coronary arteriography in cardiomyopathy.

Q waves and coronary arteriography in cardiomyopathy.

This study shows that the Q wave pattern on the electrocardiogram provides insufficient evidence for the diagnosis of ischaemic heart disease. Apparent evidence of ischaemic heart disease on the electrocardiogram was misleading in 6 out of zo patients with congestive cardiomyopathy and in 3 of 8 patients with hypertrophic cardiomyopathy. With the increasing application of surgical techniques to...

Safety of coronary arteriography.

The mortality and morbidity of coronary arteriography are presented with particular reference to the relative safety of the Sones as compared with the Judkins technique. There were 6 deaths in 400 investigations (i *5%), and all occurred with the3Judkins technique. The morbidity is analysedfor the last 250 investigations; cardiac infarction and serious dysrhythmias were more common with the Jud...

Selective coronary arteriography.

The technique of selective coronary arteriography, as described originally by Sones, was employed in 255 patients. Successful catheterization of both coronary arteries was carried out in 88% of these patients, and in the last 100 examinations both coronary arteries were entered in 95 patients. Selective coronary arteriography is a useful diagnostic tool but is a potentially hazardous form of ex...
