Dogs of both sexes aged 2 to 4 were subjected to inhalation inoculation with polymer 239Pu or submicron 239PuO2 aerosols in amounts close to acute, subacute and chronically effective ones. ECG was recorded in standard, amplified and single leads (V3). All calculations were done by lead II. Signs of the right heart overburdening were noted in the presence of the P-pulmonale complex, deep S1 wave or cardiac electrical axis of SI-SII-SIII type. Signs of the right heart overburdening were revealed after inhalation of polimer 239Pu (70%). The absence of similar changes in damage caused by 239Pu could be attributed to its fast resorption from the lungs resulting in more moderate lesion of the respiratory organs.
对2至4岁的雌雄犬进行聚合物239Pu或亚微米239PuO2气溶胶的吸入接种，剂量接近急性、亚急性和慢性有效剂量。以标准、放大和单导联（V3）记录心电图。所有计算均通过II导联进行。在出现肺型P波、深S1波或SI-SII-SIII型心电轴时，记录右心负荷过重的体征。吸入聚合物239Pu后出现右心负荷过重体征的比例为70%。239Pu造成的损伤中未出现类似变化，这可能归因于其从肺部的快速吸收，导致呼吸器官的损伤较为轻微。
