2225 Cardiac Alterations

In this episode of Nursing Student Deep Dive, we break down the cardiovascular system as a combination of pump, plumbing, valves, and electrical wiring. Instead of memorizing disconnected cardiac symptoms and rhythm strips, this episode focuses on understanding the mechanics behind cardiac output, perfusion, electrical conduction, and what happens when different parts of the cardiovascular system fail. Topics include cardiac anatomy and blood flow, preload, afterload, contractility, cardiac output, coronary circulation, ECG interpretation, sinus bradycardia and tachycardia, PACs, PVCs, atrial fibrillation, SVT, adenosine, coronary artery disease, stable and unstable angina, NSTEMI, STEMI, troponin, PCI, CABG, valve disorders, infective endocarditis, pericarditis, cardiac tamponade, and peripheral vascular disease. This episode is designed to help nursing students connect abnormal assessment findings, ECG changes, medications, and emergency interventions to the underlying cardiac physiology. The goal is to recognize when the problem involves the heart’s electrical system, blood supply, pumping ability, valves, or circulation—and use that understanding to identify deterioration and prioritize nursing care.
