Abstract
Pulsus alternans describes an arterial pulse waveform that shows alternating strong and weak beats despite a regular rhythm. Either discovered during physical examination or catheterization, pulsus alternans indicates severe left ventricular (LV) dysfunction and poor prognosis. There has been considerable debate about the underlying mechanism. We present a tracing which depicts a classic example of pulsus alternans and gives some clues about its initiation mechanism.
期刊介绍：
Catheterization and Cardiovascular Interventions is an international journal covering the broad field of cardiovascular diseases. Subject material includes basic and clinical information that is derived from or related to invasive and interventional coronary or peripheral vascular techniques. The journal focuses on material that will be of immediate practical value to physicians providing patient care in the clinical laboratory setting. To accomplish this, the journal publishes Preliminary Reports and Work In Progress articles that complement the traditional Original Studies, Case Reports, and Comprehensive Reviews. Perspective and insight concerning controversial subjects and evolving technologies are provided regularly through Editorial Commentaries furnished by members of the Editorial Board and other experts. Articles are subject to double-blind peer review and complete editorial evaluation prior to any decision regarding acceptability.
