An ECG Sensor Can Contribute To Many Different Diagnoses.

An ECG sensor has a very heavy workload in modern medicine.  Used all over the world, the ECG or electrocardiogram measures the electrical activity of the heart and can point the way towards a wide range of different issues with the main blood pump of the body. 

The heart beats in a regular rhythm to pump blood throughout the body.  It does this by contracting one area of itself to force blood out while another area relaxes to let blood in.  The rhythm is kept up by the natural pacemaker of the heart known as the sinoatrial node.  This node sends out electrical impulses that keep the heart beating regularly. 

The electrical signals can be measured and tracked, allowing doctors to follow the rhythm of the heart and determine if there are any issues.  In an ECG test, the electrical impulses made while the heart is beating are recorded and usually shown on a piece of paper. This is known as an electrocardiogram, and records any problems with the heart's rhythm, and the process of heart beat through the heart, which may reveal underlying issues.

An ECG sensor is what actually reads the electrical impulse being generated by the heart and allows that signal to be recorded and tracked.  Usually ECG’s are done when people are having trouble breathing, chest pain, or feeling like their own heart beat is abnormal.  One of the most common usages of an ECG is to look for evidence of coronary disease in the arteries. The one problem, however, is that for a number of patients the ECG recording at rest can be normal while it might be abnormal during exercise.  Because of this, there are ways to do ECG’s while a patient is exercising. 

ECG’s can show a number of different things.  They’ll show if a patient has had a heart attack, the impact heart medicines might be having on the heart, or if the heart has a slow or fast rhythm.  The test can prove thickening of the heart muscle itself from chronic high blood pressure or even if there are too few minerals in the blood.  ECG’s are non invasive, mostly comfortable (though some patients don’t enjoy the exercise part of the stress ECG’s) and easy to administer.  All in all a very impressive result from such a common ECG sensor.
