Which term means a record of the electrical activity of the heart?
An electrocardiogram (ECG or EKG) records the electrical signal from your heart to check for different heart conditions. Electrodes are placed on your chest to record your heart’s electrical signals, which cause your heart to beat. The signals are shown as waves on an attached computer monitor or printer.
What is the instrument for recording electrical activity of the heart?
A cardiac event monitor is a device that you control to record the electrical activity of your heart (ECG). This device is about the size of a pager. It records your heart rate and rhythm.
What is the meaning electrocardiogram?
Electrocardiogram: A recording of the electrical activity of the heart. Abbreviated ECG and EKG. An ECG is a simple, noninvasive procedure. Electrodes are placed on the skin of the chest and connected in a specific order to a machine that, when turned on, measures electrical activity all over the heart.
What is the scientific word for heart?
The heart muscle, or cardiac muscle, is medically called the myocardium (“myo-” being the prefix denoting muscle).
How can you tell if an ECG is abnormal?
Abnormal results can signify several issues. These include: Defects or abnormalities in the heart’s shape and size: An abnormal ECG can signal that one or more aspects of the heart’s walls are larger than another meaning that the heart is working harder than normal to pump blood.
What process is used for recording electrical activity in the brain?
Electroencephalography, technique for recording and interpreting the electrical activity of the brain. The recording produced by such an instrument is called an electroencephalogram, commonly abbreviated EEG.
What records electrical activity of the brain?
An EEG records the electrical activity of your brain via electrodes affixed to your scalp. An electroencephalogram (EEG) is a test that detects electrical activity in your brain using small, metal discs (electrodes) attached to your scalp.
What is a normal ECG reading?
Normal intervals Normal range 120 – 200 ms (3 – 5 small squares on ECG paper). QRS duration (measured from first deflection of QRS complex to end of QRS complex at isoelectric line). Normal range up to 120 ms (3 small squares on ECG paper).
What is heart in one word?
heart. / (hɑːt) / noun. the hollow muscular organ in vertebrates whose contractions propel the blood through the circulatory system. In mammals it consists of a right and left atrium and a right and left ventricleRelated adjective: cardiac.
What is the full meaning of cardiac?
1a : of, relating to, situated near, or acting on the heart. b : of or relating to the cardia of the stomach. 2 : of, relating to, or affected with heart disease cardiac patients. cardiac.
What if ECG report is abnormal?
An abnormal ECG can mean many things. Sometimes an ECG abnormality is a normal variation of a heart’s rhythm, which does not affect your health. Other times, an abnormal ECG can signal a medical emergency, such as a myocardial infarction /heart attack or a dangerous arrhythmia.
Can ECG detect heart blockage?
However, it does not show whether you have asymptomatic blockages in your heart arteries or predict your risk of a future heart attack. The resting ECG is different from a stress or exercise ECG or cardiac imaging test.
