Graph paper, quad-ruled paper, graphing paper or millimeter paper is writing paper that is printed with fine lines making up a regular grid. The lines are often used as guides for plotting mathematical functions or experimental data and drawing diagrams. It is commonly found in mathematics and engineering education settings and in laboratory notebooks.

Interpreting an EKG  

ECGs can be doctors in the diagnosis and determination of current or past heart abnormalities and are often a regular screening for people with heart disease. With electrodes attached at various strategic body points, the EKG machine, the electrical impulses of the heart. The results of the pulses are displayed on a computer screen and then on graph paper. The attending physician or EKG technician interprets your heart health by reading the graphed EKG image.

ECGs are an important tool for doctors to diagnose and treat heart ailments. The EKG reading of the heart is compared to the reading of a standard /normal hearts, to build a picture of your heart function. Abnormalities in heart rate, heart rhythm or contractions and relaxations may signal the presence of past heart attack, heart disease or coronary artery disease.

Interval represents a bridge between the contracting and relaxation of the atria. Each ECG has several other spikes and dips, the hearts electrical waves, each spike or DIP is covered by an alphabetical letter.

The majority of normal hearts have a pattern with a slightly different rhythm. This is called sinus arrhythmia and is considered normal and healthy. The absence of sinus arrhythmia may indicate other problems with the heart. In ECG-interpretation, the lack of sinus arrhythmia was seen to predict the occurrence of sudden death from heart attack or heart failure. The results of an ECG can be the basis for further treatment. Your doctor will decide whether further assessment is required. EKG technicians are highly trained and qualified medical professionals, many of these doctors to technicians of the first body in the interpretation of ECG results.

If you have an ECG performed, your technicians will be happy to answer questions in relation to the ECG reading. If you notice that something seems abnormal to you, the technicians, you can calm your fears and explain the results in layman's terms.
