The authors at first made formula from which assumed normal cardiac size could be calculated in reference to body-weight and length. Actual cardiac size/assumed normal cardiac size was called dilatation-gradient : actual cardiac size was measured by planimeter in its shadow in the direct postero-anterior projection of X-ray. Relatiohship between circulation time and dilatation-gradient was investigated in cases of congestive heart failure and non-congestive cardiac disease, and linear relationship was demonstrated between them. This does not mean that prolongation of real circulation time (decrease of blood velocity) is due to dilatation of heart. Because circulation-time, clinically used, shows not only the blood velocity but also the degree how much the drug injected is diluted by blood.

During admission for investigation of dysphagia, an 82-year-old woman suddenly complained of dyspnea, which was followed by cardiogenic shock. Her symptoms, electrocardiogram, echocardiogram and laboratory data were compatible with an extensive acute anterior myocardial infarction. Emergency cardiac catheterization showed no atheromatous narrowing in any coronary artery. However, the contractions of the left and right ventricles were diffusely and severely impaired, except for some hyperkinesis of the basal area. The asynergy, as well as the abnormalities on the ECG, improved almost to normal by the 35th hospital day. An endomyocardial biopsy from the right ventricle during the acute phase showed atypical myocardial damage with proliferation of fine collagen fibers and small round-cell infiltration including polymorphologic leukocytes. This type of transient cardiac disorder has recently been described in Japan, and is called ‘Tako-tsubo cardiomyopathy’ because of the characteristic appearance of the left ventricular asynergy. In the present case, ventricular asynergy was not limited to the left ventricle, but was also present in the right ventricle.
