This case illustrates that premature ventricular contractions can initiate transient worsening of pulsus alternans in patients with severe heart failure, such as peripartum cardiomyopathy.

Alerts clinicians to possible PVC-triggered pulsus alternans worsening in peripartum cardiomyopathy; leaves open generalizability and management implications.
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.
