T cells or T lymphocytes are a type of lymphocyte (in turn, a type of white blood cell) that plays a central role in cell-mediated immunity. They can be distinguished from other lymphocytes, such as B cells and natural killer cells (NK cells), by the presence of a T-cell receptor (TCR) on the cell surface.

The electrical activation of the heart can be picked up (detected) using skin electrodes strategically placed on the body. The placement of these electrodes gives us the leads we use in recording an ECG.
