Latent Period Between Electrical and Pressure Pulse Waves Corresponding to Right Auricular Systole. ∗

Abstract

Summary

In 8 adult subjects with essentially normal hearts the latent period between the beginning of the electrical P wave and pressure pulse wave corresponding to the right auricular systole averaged 0.11 sec. 2. In one case of a child with a rapid pulse and Tetralogy of Fallot the latent period was much shorter, 0.055 sec. 3. In one case of scleroderma with pulmonary hypertension and partial heart block the latent period was prolonged to 0.17 sec.
