An electrocardiogram (ECG or EKG) is a quick test to check the heartbeat. It records the electrical signals in the heart. Test results can help diagnose heart attacks and irregular heartbeats, called arrhythmias. ECG machines can be found in medical offices, hospitals, operating rooms and ambulances.
Electrocardiography is the process of producing an electrocardiogram (ECG or EKG[a]), a recording of the heart's electrical activity through repeated cardiac cycles. [4] . It is an electrogram of the heart which is a graph of voltage versus time of the electrical activity of the heart [5] using electrodes placed on the skin.
An electrocardiogram (EKG/ECG) uses temporary electrodes on your chest and limbs to monitor, track and document your heart’s electrical activity (which controls your heartbeats) for diagnostic purposes. A computer translates the information into a wave pattern your healthcare provider can interpret. This is a quick, noninvasive test that ...
An electrocardiogram — abbreviated as EKG or ECG — measures the electrical activity of the heartbeat. With each beat, an electrical impulse (or “wave”) travels through the heart. This electrical wave causes the muscle to squeeze and pump blood from the heart.
An electrocardiogram, also called an ECG or EKG, is a simple and painless test that measures the electrical impulses of your heart to check for signs of heart disease. It's done through small...
An electrocardiogram (ECG) represents the electrical current moving through the heart during a heartbeat. The current's movement is divided into parts, and each part is given an alphabetic designation in the ECG. Each heartbeat begins with an impulse from the heart's pacemaker (sinus or sinoatrial node).
The electrocardiogram (abbreviated as ECG or EKG) represents an electrical tracing of the heart and is recorded non-invasively from the surface of the body. The word ECG derives from the German language. In German, it is elektro-kardiographie.
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 (EKG) is a painless process that records the heart's electrical activity. Small metal electrodes are placed on the person's wrists, ankles and chest. The electrical signals travel from the electrodes through wires to the EKG machine, which transforms the signals into patterns or waves.
An ECG measures these changes in electrical signals (or, in fact, voltage) on different areas of skin and plots them as a graph. The resulting ECG graph is called an electrocardiogram. Go to: When is an ECG done? An ECG is used to check how the heart is functioning.
