Schematic representation of normal ECG In electrocardiography , the ST segment connects the QRS complex and the T wave and has a duration of 0.005 to 0.150 sec (5 to 150 ms). It starts at the J point (junction between the QRS complex and ST segment) and ends at the beginning of the T wave.
The ST segment starts from the J point (termination of QRS complex and the beginning of ST segment) and ends with the T wave.The ST segment is the plateau phase, in which the majority of the myocardial cells had gone through depolarization but not repolarization.
The superconducting tunnel junction (STJ) – also known as a superconductor–insulator–superconductor tunnel junction (SIS) – is an electronic device consisting of two superconductors separated by a very thin layer of insulating material. Current passes through the junction via the process of quantum tunneling.

Also, it can be a normal variant or artifacts, such as: Pseudo-ST-depression, which is a wandering baseline due to poor skin contact of the electrode [3] Physiologic J-junctional depression with sinus tachycardia [3] Hyperventilation [3] Horizontal ST depression in V4, V5, V6 leads during a cardiac stress ECG. Other, non-ischemic, causes include:

What we want is a cholesterol level that is normal for the human species, which is considered to be around 30 to 70 mg/dL (or 0.8 to 1.8 millimoles per liter).
