Pulsus alternans, the alternating strong and week pulses which occur in patients with severe heart failure, was first described by Traube in 1872. Since then various methods, both invasive1,2 and non-invasive3,4, have been used to study this phenomenon. This study demonstrates the utility of using simultaneous electrocardiography (ECG) and Doppler echocardiography to document pulsus alternans, and to differentiate it from other causes of alternating pulses.
交替脉，即重度心力衰竭患者出现的强弱交替的脉搏，于1872年由特劳贝首次描述。从那时起，多种方法，包括有创和无创方法，已被用于研究这一现象。本研究证明了同时使用心电图（ECG）和多普勒超声心动图记录交替脉，并将其与交替脉的其他原因相鉴别的实用性。
