EKG
Human body systems depend upon electrical impulses to send and receive messages. electrical energy is what directs and choreographs the rhythmic beating of your heart. Each beat is initiated by an electrical signal. This electrical activity can be monitored and record in the form of a graph. The graph made in this process is called an electrocardiogram and is abbreviated as EKG or ECG. Medical professionals are trained to study an EKG and use the graphical display to diagnose heart abnormalities such as irregular heartbeat, irregular speed of contractions, angina (chest pain that can indicate tussle damage), or even tissue death (myocardium infarction, also known as a heart attack).
