Medical Physics equipment (Implantable cardioverter defibrillator) question to Physics (Electricity and Magenetism)

Instruction : Select a medical investigation or scientific/engineering equipment (Use Implantable cardioverter

defibrillator) , that is based on physicsconcepts/principles studied. Briefly describe investigation (or equipment), then

explain how it works. You should discuss your topic with sufficient detail and concision as to present a unified whole.

Be specific rather than vague, concise rather than repetitive. Include the physical quantities you need to define in order

to describe how the equipment functions/the investigation measures and the principles/laws that apply. Estimate or look

up some of the values of the physical quantities involved and calculate others by using formulas from the formula sheet

Answer the question in the following parts:

Part 1: Theory of Implantable cardioverter defibrillatorin clinical practices (Examples) and how it is correlated with the concepts of electric fields/currents etc and the formulas

Part 2: Calculations with specific values and formulas along with explanations

(Include a table that incorporate columns of formulas, theory and application with calculations)

****** References are below, but please also search for more references, data, papers or information that involves values and figures that can be used for calculations for theory applied to the Implantable cardioverter defibrillator.
