[Ultrasonography in sternal fractures].

Conventional radiography is the widely accepted diagnostic method in patients after the sternal trauma, but the fracture cannot always be detected. Sonography, that is not able to demonstrate deeper portions of the bone, allows imaging its cortex proximal to the transducer as an intense hyperechoic interface with distal shadowing. Its disruption as a result of the trauma can be well seen, especially in flat bones.

[Arrhythmias in healthy sailors].

Results are presented of 24-hour monitoring by Holter's method of ECG in 50 healthy seamen aged 29-55 years (mean 47.7 years), in whom clinical examination, chest radiography, resting ECG records, and echocardiography confirmed normal condition of the cardiovascular system. In 36% of the seamen premature beats of various origin were elicited.
