Excerpt
Stokes was apparently the first to describe atrial sounds (1), and Webster (2) was probably the first to record transmitted waves in the radial pulse. The purpose of the following report is to describe the presence of distinct double atrial sounds and to discuss the nature of atrial impulses recorded over the left radial artery in a patient with heart block.
CASE REPORT A 65-year-old man entered Thayer Veterans' Administration Hospital on March 23, 1961, because of extreme "weak spells" and "staggering" that he had experienced during the week before his admission. His local physician had told him that his

Summario in Interlingua
Distincte duple sonos atrial e impulsos atrial transmittite a arterias peripheric esseva registrate in un masculo de 65 annos de etate con bloco cardiac. Le prime sono atrial occurreva 0,10 secundas post le initiation del dispolarisation atrial e le secunde 0,24 secundas post ille puncto. Sonos atrial non esseva registrate durante le systole ventricular, sed quando le systole atrial occurreva immediatemente ante le dispolarisation ventricular, le sono atrial se fundeva con le prime sono cardiac e le resultante combination esseva un sono intensificate. Transmittite impulsos atrial registrate supra arterias peripheric appareva approximativemente 0,16 secundas post le initiation del dispolarisation atrial. Viste que le impulsos atrial esseva abolite per un pression de 100 mm de Hg, il es proponite que illos esseva transmittite mechanicamente e que illos non esseva de origine neuromuscular.
