In this episode of TechPrep: Rapid PTCB Review, we review atrial fibrillation and venous thromboembolism with a focused, exam-relevant approach tailored to pharmacy technician practice and the PTCB exam. Learners will explore the pathophysiology of abnormal cardiac rhythm and clot formation, how these conditions increase the risk of stroke and other complications, and how they connect directly to anticoagulant and rate/rhythm control therapy.

The episode links disease fundamentals to commonly prescribed medications, including anticoagulants, antiplatelet agents, and rate-control therapies. Emphasis is placed on mechanisms of action, therapeutic monitoring, safety concerns, and high-alert medication handling—key areas for pharmacy technicians supporting cardiovascular patients.
