In studying a large group of women with hypertension, it will be found that a considerable number exhibit striking arterial pulsation phenomena in the right supraclavicular region and in the episternal notch. The first and most common example of cervical arterial pulsation is the systolic thrust of the aorta in the episternal notch. This expansile elevation of the aortic arch may be palpable, with visible pulsation lacking, and often a very definite pulsating mass may be observed pressing the loose areolar tissue of the episternal area upward, simulating somewhat an aneurysmal dilatation. Sometimes this is accompanied by subjective disagreeable sensations. The second type of arterial pulsation in cases of hypertension is that resulting from elevation of the subclavian artery; this is not so striking as those affecting the aorta or the common carotid. More information may be elicited relative to the subclavian pulsations by palpation than by inspection. The third
