One of the most interesting problems occupying our attention of late years has been that of arterial tension in relation to circulatory disease. While the greater number of conditions fall, we believe, without difficulty into our classification into three cardinal groups, still there are certain outside cases which it is necessary to consider. One of these is "Constitutional Low Arterial Tension," and that is the topic we have chosen to present to this section under the title of this paper.
The cardinal groups, which as a matter of clinical experience we have come to recognize are:
Primary low arterial tension, covering all cases in which the tension in the arteries is abnormally low on account of valvular disease, myocardial disease, or secondary to some general weakening condition.
High arterial tension, in which is found an abnormally increased tension in the arteries due to some condition of the system demanding it.
