To thrive as a Cardiac PCU RN, you need strong cardiac nursing knowledge, advanced patient assessment skills, and an active RN license with relevant experience in progressive care or telemetry units. Familiarity with cardiac monitoring systems, EKG interpretation, and certifications such as ACLS (Advanced Cardiovascular Life Support) are typically required. Excellent critical thinking, teamwork, and communication skills help RNs manage complex cardiac patients and collaborate with multidisciplinary teams. These competencies are essential to ensure patient safety, prompt intervention, and optimal outcomes in the high-acuity cardiac progressive care environment.
