Print. Uterine prolapse is when the uterus drops down into the vagina, and in severe cases, outside the vagina. It is one of the more distressing gynecologic conditions and spares no age group.
In most leads, the T wave is positive. This is due to the repolarization of the membrane. During ventricle contraction (QRS complex), the heart depolarizes. Repolarization of the ventricle happens in the opposite direction of depolarization and is negative current.
The depolarization and repolarization of the SA node and the other elements of the heart's electical system produces a strong pattern of voltage change which can be measured with electrodes on the skin. Voltage measurements on the skin of the chest are called an electrocardiogram or ECG.
