Ep 3: Electrophysiology Explained: From Resting Potential to Electrical Chaos 06.02.2026 35:20

In this episode of Paging Dr. Samir , we take the next step from transport and gradients into electrophysiology—the rules that determine when cells fire, when they stay silent, and when electrical systems fail without warning. Dr. Samir breaks down resting membrane potential, thresholds, action potentials, repolarization, and refractory periods as clinical decision points rather than abstract wave...

Ep 2: Electrolytes Aren’t Numbers: Membranes, Gradients, and Why Cells Fail First 06.02.2026 32:46

In this episode of Paging Dr. Samir , we move from homeostasis down to the cellular level to explain why organ failure always starts with membrane failure. Dr. Samir characterizes cell membranes as control interfaces, not anatomical diagrams, and explains how transporters, pumps, and gradients drive excitability, fluid shifts, and electrical stability. Using real clinical examples like hyperkalemi...

Ep. 1: Homeostasis: Why Your Body is a Control Freak (and Why That Saves Your Life) 04.02.2026 39:39
