A system and method for obtaining a nuclear kymogram of regional wall motion of an organ under study such as a human heart includes injecting a radioisotope into the blood stream which accumulates in the cardiac blood pool or myocardium. A scintillation camera having a reduced generally elongated area of data recordation is positioned overlying a selected portion of the heart and positional ''events'' occurring along the major axis of the area of recordation are swept across a crt in synchronism with the ecg signal. Successive real-time displays each in synchronism with the ecg signal are accumulated to provide a nuclear kymogram.
