Experiences with Pulsus Alternans
Ventricular Alternation and the Stage of Heart Failure
Three years' experience with pulsus alternans, including its production with exercise, has shown that alternans may exhibit at least 3 types of behavior, and has led the authors to believe that the type of behavior a patient presents is related to the degree of heart failure present. Those patients who developed alternans following exercise were not in cardiac failure clinically, and yet hemodynamic data indicated myocardial insufficiency. A sustained pulsus alternans at rest seems to have no special prognostic significance in heart failure.
