The Pulse (Diagnostic Pulse Theory)
Press two fingers to the wrist and the body confesses: its speed, its strength, its faltering rhythm spell out the disease within.
Ancient physicians discovered that the arteries beat with a rhythm that the trained hand could read like a text. By attending to how fast, how forceful, how full, and how regular the pulse felt beneath the fingers, a doctor could judge the inner state of the patient and forecast the turns of an illness. Galen turned this art into an elaborate science, sorting pulses into dozens of named types and writing whole treatises on how to interpret them. His system dominated bedside diagnosis in Europe and the Islamic world for well over a thousand years.
