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.
V4 placement is at the 5. th intercostal space in. line with the mid-clavicle. Do not use the nipple as a landmark. When obtaining a. right sided ECG, simply move only V4 to the same landmarks but on the right. side of the chest wall, this lead now becomes V4R. ï· Now place V3 in a straight line between V2 and V4 directly over the 5th rib. ï· Skip V5 and go to V6 placement.
