MCL may mean medial collateral ligament or modified chest lead, depending on context.

There are only 10 electrodes and leads, but those 10 leads get 12 different electrical recordings, which makes it a 12-lead ekg.
A twelve lead electrocardiogram (EKG or ECG) shows a representation of the electrical activity of the heart as measured from 12 different perspectives (leads). The interpretation of EKGs allows a physician to determine if there are potential abnormalities or injury to the heart, at the time the EKG is taken.
12, one for each lead.
ECG and EKG mean the same thing, and it records the hearts electrical activity on a 6 second strip. The physician can make a diagnosis by looking at the EKG print out. If a 12-Lead EKG is used, then all walls and function of the heart will be recorded.

An EKG tells us about how electricity flows through the cells of the heart. Any infarction of cardiac tissue causes changes in the way the electricity travels. An EKG can show us these changes and help us to even identify where the infarction is occurring. A 12 lead EKG must be done to truly identify any infarction. The 12 lead shows us 12 different views of the electricity as it moves from one lead to another. By comparing the views we get against what would normally be expected and comparing each lead to the others we can look for changes in the EKG pattern (ST elevation or depression is the most obvious, but many other changes exist).
