An electrocardiogram (ECG or EKG) is a test to record the electrical signals in the heart. It shows how the heart is beating. Sticky patches called electrodes are placed on the chest and sometimes on the arms or legs. Wires connect the patches to a computer, which prints or displays results.
EKG comes from the German spelling, elektrokardiogramm. Your doctor might use the term EKG to avoid confusion with an EEG, a different type of medical test that measures brain waves.
An electrocardiogram (EKG/ECG) is a quick test that checks your heart’s rate and rhythm. It records your heart’s electrical signals and helps diagnose arrhythmias.
Electrocardiography is the process of using an electrocardiograph (a device) to produce an electrocardiogram (a recording, often called an ECG or EKG[a]) that shows a line graph of the heart's electrical activity through repeated cardiac cycles. [4] .
An electrocardiogram (ECG or EKG) is one of the simplest and fastest tests used to evaluate the heart. Electrodes (small, plastic patches that stick to the skin) are placed at certain spots on the chest, arms, and legs. The electrodes are connected to an ECG machine by lead wires.
An electrocardiogram is a test that measures electrical waves in the heart. An EKG is used to diagnose many heart conditions, including heart attack. What is an electrocardiogram? An electrocardiogram measures the electrical activity of the heartbeat. With each beat, an electrical wave travels through the heart.
Being able to read an EKG or ECG is an important skill for nurses. But looking at a 12-lead EKG/ECG can put your own heart into a lethal rhythm. Nurses are usually the first ones to read that “hot off the press” EKG tracing. This article will explain everything you need to know about EKG readings.
