Day-case arteriography.

Outpatient femoral arteriography has been carried out in 100 consecutive patients presenting with evidence of peripheral vascular disease. Patients have been observed for seven hours in an observation ward bed. No bleeding or other complications have been encountered. The cost-saving to the hospital is approximately 60.00 pounds per case. More importantly, the service to patients has been improved, with less chance of last minute cancellation due to unavailability of a surgical bed.

Deficient slowing of the heart among very heavy social drinkers.

Very heavy social drinkers demonstrated less slowing of their heart rate than controls while exhaling after a maximal inhalation. While this suggests defective autonomic control of the heart, clarification of the mechanism and significance of this reflex and its impairment must await sophisticated study.

The abnormal heart rate response to a deep breath in borderline labile hypertension: a sign of autonomic nervous system dysfunction.

A group of patients with borderline or labile hypertension were prospectively recruited and asked to take a deep breath while lying supine and being monitored by electrocardiography. Their attenuated heart rate responses were sharply abnormal, demonstrating an excessively rapid rate throughout but without quickening on inspiration nor slowing with expiration. It is suggested that this further demonstrates inadequate autonomic control, sympathetic and parasympathetic, of the heart in labile hypertension and even at a moment when the patient's blood pressure is normal.
