As an RDCS, your daily tasks typically include performing echocardiograms, preparing patients for procedures, analyzing cardiac images, and collaborating with cardiologists to discuss findings. You may also be responsible for maintaining ultrasound equipment, documenting results in patient records, and explaining procedures to patients to help them feel comfortable. The role often involves working closely with both adult and pediatric populations, depending on the facility. While most work is scheduled, some on-call or urgent cases may also arise, adding variety to the typical workweek.
