Q. What does a EKG test for?
Doctor Answer is medically reviewed by SecondMedic medical review team.
An electrocardiogram (EKG) is a test that takes detailed electrical measurements of your heart. It's typically used to diagnose or monitor conditions such as arrhythmia, conduction abnormalities, and coronary artery disease.
An EKG works by detecting the electrical activities generated by your heart muscle as it contracts and relaxes. It records these electrical signals through electrodes placed on various spots on the body - usually around the chest area and sometimes along the limbs. The machine measures the voltage between each pair of electrodes to produce a graphical representation of your cardiac activity across time - known as an electrocardiogram tracing or simply an EKG tracings.
The trace shows variations in intensity over time which allow doctors to evaluate several aspects of cardiac health including:
• Heart rate: The number of times per minute that your heart beats (pulse), which is determined by measuring how far apart successive R-waves are in your ECG tracing;
• Rhythm: Whether or not your heartbeat follows a regular pattern – ie., if you have atrial fibrillation or something like it;
• Wave amplitudes: This refers to the size and shape of specific waves in relation to one another, which can indicate whether there's adequate blood flow being conducted through one’s arteries;
• Voltages: A measure of how much electricity was produced when certain parts were stimulated during testing;
• Other electrical activity from outside sources can also be picked up such as artificial pacemakers and abnormal rhythms caused by disease processes).
With an EKG test, medical professionals can quickly identify issues with patient's hearts before they become too serious – helping them provide better preventive care for those who need it most!
