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.
Your doctor will diagnose a heart attack based on your signs and symptoms, your medical and family histories, and test results. An EKG is a simple, painless test that detects and records the heart's electrical activity. The test shows how fast the heart is beating and its rhythm (steady or irregular). An EKG also records the strength and timing of electrical signals as they pass through each part of the heart. An EKG can show signs of heart damage due to coronary heart disease (CHD) and signs of a previous or current heart attack.
