VI. PULMONARY HEART DISEASE

IN ACUTE experiments performed on dogs wherein he completely damaged by cauterization the musculature of the right ventricle, Bakos²⁶⁸ observed no changes in the peripheral venous and systolic and diastolic pulmonary arterial pressures following the injury as compared to the control level of these pressures recorded prior to the cauterization. Because of the continuity of the circumscribing individual ventricular muscle bands, the myocardium of the left ventricle mechanically transmitted its energy to the right ventricle so that the latter chamber passively functioned as an efficient force pump despite complete inactivation of its myocardium. From these studies it seemed apparent that the function of the two ventricles could not be dissociated, since the anatomy of the distinct myocardial bands made inescapable the unified function of both chambers. Kagan,²⁶⁹ however, has adduced experimental evidence from similar studies that the activity of the ventricles is maintained by quite separate . . . [Full Text PDF of this Article]
