Cushing’s Triad, Stress-Induced Cardiomyopathy & Autonomic Reflexes Explained | UWorld Concept

Описание: When hypoxia leads to neuronal injury and cerebral edema, intracranial pressure (ICP) rises. This triggers Cushing’s Triad —
🧠 ↑ Blood Pressure, ❤️ ↓ Heart Rate, and 🌬️ Irregular Breathing — a compensatory response to maintain cerebral perfusion.

Excess catecholamine release, especially in postmenopausal women, can cause stress-induced (Takotsubo) cardiomyopathy — a reversible condition showing ischemic-like ECG changes without coronary blockage.

In spinal cord injury, sympathetic pathways are disrupted, leading to hypotension and bradycardia (neurogenic shock).
And with aging, the SA node loses pacemaker cells, reducing its ability to meet the body’s demand — causing slower heart rates.

This video covers all these autonomic and cardiovascular adaptations in one clear, UWorld-style explanation.
