At a particular point in time, lead I is measured as 0.82 mV and lead II is measured as 0.91 mV. Calculate the value of lead III, the magnitude of the cardiac vector, and the angle of deflection.

1. Using the Hodgkin–Huxley model, calculate the flow of sodium ions through voltage-gated sodium channels in a membrane

at the onset of depolarization. Assume that a membrane

in the human body has a surface area of 1mm2 and 75 sodium channels. The threshold membrane potential for sodium channels is -65mV. The membrane resistance of one sodium channel is 250GΩ.
