The carotid and ECG pulses as indices for nuclear cardiography imaging

Nuclear cardiography has emerged from nuclear medicine to help the cardiologist in assessing the heart's performance. One of the examinations practiced is imaging of the cardiac muscle at its two extreme phases: End-Systole (ES) and End-Diastole (ED). Images of those two phases of the cardiac cycle may provide information for the calculation of Ejection Fraction (EF) and the asynergy and dysynergy of the heart muscle.
