Pulsus alternans in organic heart disease indicates definite sign of severe myocardial injury and/or left ventricular failure. Pulsus alternans in one case suspected primary myocardial disease was studied. Simultaneous recordings of electrocardiogram, phonocardiogram and carotid pulse wave had been frequently performed during hospitalization. Systolic time intervals were measured by Blumberger-Holldack's method. Small systolic wave in pulsus alternans demonstrated markedly prolonged DAZ (ICT: isovolumic contraction time) and ASZ (PEP: pre-ejection period), shortend ATZ (ET: ejection time), decreased ATZ/ASZ (ET/PEP) and unchanged UFZ (Q-I: electro-mecha-nical coupling interval) and Q-II (electro-mechanical systole) compared with large systolic wave. Marked dicrotic carotid pulse wave was shown in small systolic wave. Alteration of systolic time intervals and dicrotic wave in pulsus alternans was discussed cardiodynamically on the base of myocardial contractility.
