This video is one of around 310 titles, originally broadcast on Channel 7 of the ILEA closed-circuit television network, given to Wellcome Trust from the University of London Audio-Visual Centre shortly after it closed in the late 1980s. Although some of these programmes might now seem rather out-dated, they probably represent the largest and most diversified body of medical video produced in any British university at this time, and give a comprehensive and fascinating view of the state of medical and surgical research and practice in the 1970s and 1980s, thus constituting a contemporary medical-historical archive of great interest. The lectures mostly take place in a small and intimate studio setting and are often face-to-face. The lecturers use a wide variety of resources to illustrate their points, including film clips, slides, graphs, animated diagrams, charts and tables as well as 3-dimensional models and display boards with movable pieces. Some of the lecturers are telegenic while some are clearly less comfortable about being recorded; all are experts in their field and show great enthusiasm to share both the latest research and the historical context of their specialist areas.

Segment 1 Gilliland introduces Lever. Lever shows a graph showing blood pressure results of the normal population. Time start: 00:00:00:00 Time end: 00:05:06:00 Length: 00:05:06:00

Segment 2 Lever talks through a table listing the risk factors for developing hypertension. A graph is shown which details how treatment for high blood pressure reduces the risk of medical complications. Lever discusses epidemiological studies of hypertension and their findings. Time start: 00:05:06:00 Time end: 00:12:29:00 Length: 00:07:23:00

Segment 3 Lever discusses what should be looked for when examining a patient with potential hypertension. Slides of a woman with Cushing's syndrome are shown. Time start: 00:12:29:00 Time end: 00:17:25:00 Length: 00:04:56:00

Segment 4 Lever discusses what to expect at the end of a first visit of a hypertensive patient to a clinic and how to proceed according to the findings. A table is shown which lists investigations to be made on a patient with confirmed hypertension. An intravenous pyelogram of a patient with severe hypertension is shown. Time start: 00:17:25:00 Time end: 00:23:34:00 Length: 00:06:09:00

Segment 5 Lever refers to a table showing electrolyte patterns in a patient with primary and secondary hypertensive conditions then a table showing the causes of hypokalaemia in hypertension. He then describes the mechanism of primary aldosteronism. Time start: 00:23:34:00 Time end: 00:31:37:00 Length: 00:08:03:00

Segment 6 Lever shows a table listing treatment options for primary, then secondary, hyperaldosteronism. A case study is given of a man with severe secondary hyperaldosteronism. Time start: 00:31:37:00 Time end: 00:37:30:00 Length: 00:05:53:00

Segment 7 Lever shows a chart in which diagrammatic comparisons between primary and secondary hyperaldosteronism are given. A table is shown in which different drug treatments for hypertension are given. A final table is shown which details the main points made in the lecture. Time start: 00:37:30:00 Time end: 00:43:55:06 Length: 00:06:25:06
