By means of the fluoroscope the action of the heart may bewatched, and occasionally information is obtained that might other-wise be overlooked. The rapidity and vigor of the pulsations are,of course, noted. Arhythmia is occasionally seen. I have fluoroscoped one case Grier: X-Ray of Heart and Great Vessels 171 of heart block, and the demonstration was very beautiful. The slow,massive contractions of the left ventricle occurred about twentytimes to the minute, while the contractions of the right auriclewere so rapid as to almost challenge the power of the eyes to followthem.
