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.
An electrocardiogram - or ECG - is a simple and useful test which records the rhythm and electrical activity of your heart. Small sticky patches called electrodes are put on your arms, legs and chest. These are connected by wires to an ECG recording machine which picks up the electrical signals that make your heart beat. This electrical activity is recorded and printed onto paper.
