Abstract

Royal Canadian Mounted Police (RCMP) cadets experience high volumes of potentially psychologically traumatic events, suggesting a need of normal cardiac cycle interval data on the cadets for comparison. We characterize the cardiac cycle of incoming RCMP cadets starting the 26-week training program. The cadets collected their cardiac data using the LLA Recordis™ device. Male RCMP cadets had higher (p<0.05) myocardial and diastolic performance indices, aortic valve open to aortic twist time, and isovolumic relaxation time than female RCMP cadets. Monitoring the cardiac cycle intervals in RCMP cadets can provide insights to changes in their heart function from their occupational demands.
