💡 Bilateral BP: 30 Seconds That Save Lives

Aortic dissection = the great mimicker. Only 0.1-0.2% of chest pain, but 1-2% mortality per hour.

Classic triad:
• Sudden, severe "tearing" pain → back
• BP differential >20mmHg between arms
• Pulse deficit

When in doubt, take BP in both arms. It takes 30 seconds and could identify a surgical emergency.
