A 24-year-woman, gravida 2 para 1, 37 weeks of gestation, was admitted due to spontaneous rupture of membranes. Her previous pregnancy was uncomplicated and delivered at term via vaginal delivery. 24 hours since rupture of her membranes, no spontaneous labour was noted, hence a syntocinon/oxytocin infusion (10 units in 1L of Hartmann solution) was started at 3DmL/hour and increased to 120 mL over 9 hours. After 10 hours of infusion, during which Syntocinon dosage was increased to 30 units per litre, contractions were noted. Which is the most common complication of Syntocinon infusion?
