In a clinical trial monitoring cardiac output and systemic blood transport, a digital vascular scanner recorded 23,840 cardiac cycles across a cohort of patients. The scanner detected that 6.8% of these cycles exhibited a premature ventricular contraction (PVC), which temporarily reduced blood transport efficiency.
Calculate the number of cardiac cycles that exhibited a premature ventricular contraction. Show your working and round your answer to the nearest whole number.
