Practice question
Question
The ECG recorded by different leads is analysed on the basis of variation of electrical potential at various loci on the surface of the body, and the time scale relation of different waves. After analysing the ECG, following particulars of heart are proposed to be obtained A. Stoke volume and cardiac output B. Volume and pressure changes during cardiac cycle C. Anatomical orientation of heart D. Various disturbances in the rhythm and conduction of cardiac excitation E. The extent, location and progress of ischemic damage to myocardium Which one of the following combinations represents both INCORRECT particulars of heart?
Explanation
In the ecg recorded by different leads is, A and B represents established outcome. functional assays confirms option A (A and B) as correct, while alternatives misstate substrate or regulatory direction, contradicting textbook data.
