CH1: Pacemaker Voltage Pulse (V) CH2: Thermal Current Drift (mA)

Historical Engineering Context: Otis Boykin developed precision wirewound resistors with an extremely low Temperature Coefficient of Resistance (TCR). Previous resistors drifted drastically with body heat (-40°C to +125°C range), causing lethal timing shifts in early pacemakers. Boykin's patent saved countless lives.
