Pulsus alternans is a rare condition characterized by alternation between strong and weak pulses during regular heart rhythm. Although pulsus alternans occurs mostly in severe heart failure, it can also be seen in other conditions that alternate ventricular contraction such as rapid tachycardia and extrasystole. Here, we report the case of a patient with peripartum cardiomyopathy who developed worsening pulsus alternans after a premature ventricular contraction.
交替脉是一种罕见的情况，其特征是在规则心律期间脉搏强弱交替。虽然交替脉大多发生在严重心力衰竭中，但也可见于其他导致心室收缩交替的情况，如快速性心动过速和期前收缩。在此，我们报告一例围产期心肌病患者，该患者在室性期前收缩后出现交替脉加重。
