A simple method of weighing the heart.

A simple method of dividing and weighing the heart is described. It is quick to perform and ratios between the left and right ventricles and the total weight of the heart are remarkably constant. Analysis of 788 cases shows that these ratios are of value in the diagnosis after death of systemic and pulmonary hypertension. This is applicable to both sexes at all ages. An unexpected finding was a significant correlation between pulmonary hypertension and acute massive pulmonary embolism, of which the prophylactic and therapeutic implications are mentioned. The value of the method in childhood and infancy is indicated.
