General Science (Physics, Chemistry, Life Sciences) & Basic Computer Knowledge
State the physics principles behind the ECG: voltage, current, Ohm's law, and the dipole model of cardiac electrical activity.
Explain how electrodes convert ionic current in tissue to a measurable potential difference and why signal amplitude depends on lead orientation.
