[Calculation of the systolic time as an index of thyroid performance].
Two methods for determining some features of cardiovascular behaviour in dysthyroidism are compared: time of appearance of the femoral sphygmic wave (as an expression of the cardiovascular response to thyroid hormones); systolic times, particularly tension time (as an expression of the contractile function of the myocardium only). Results in 52 euthyroid, hyperthyroid and hypothyroid subjects showed that systolic times (especially tension time) are more accurate and more discriminating in the assessment of thyroid performance. Measurement of this interval is thus proposed as an index for the appraisal of myocardial contractility in dysthyroidism, and as an additional means of evaluating thyroid performance.
