What is an EKG?
An EKG, or electrocardiogram, is a medical test that measures the electrical activity of the heart over a period. It provides critical information about heart rhythm, the size of the heart chambers, and the presence of any heart disease. The test is non-invasive and typically takes only a few minutes to complete.
Components of an EKG
An EKG consists of several key components that reflect the heart's electrical cycle:
1. P Wave: Represents atrial depolarization.
2. QRS Complex: Reflects ventricular depolarization.
3. T Wave: Indicates ventricular repolarization.
4. U Wave: Sometimes seen, representing repolarization of the Purkinje fibers.
Understanding these components is crucial for interpreting EKG readings effectively.
