Symptoms of brain tumours affecting the Frontal Lobe. The frontal lobes determine personality and contain the area called the motor cortex that controls movement of the muscles of the body (the motor cortex on the right half of the brain controls the left side of the body and vice versa).
Electrocardiogram Definition. A recording of the electrical activity of the heart. Abbreviated ECG and EKG. An ECG is a simple, noninvasive procedure. Electrodes are placed on the skin of the chest and connected in a specific order to a machine that, when turned on, measures electrical activity all over the heart.
Electrocardiogram records the electrical activity of your heart. An EKG (or electrocardiogram) is an electrical representation of the cardiac activity as detected by surface electrodes placed in specific locations across the chest and extremities. These electrodes detect the electrical activity occurring in the heart and these are depicted as deflections of a line.
