What is a fourth degree heart block?
artifact in ECG
Wax coated graph sheets are used for ecg recording why?
A
What is the Einthoven triangle?
The Einthoven triangle is an equilateral triangle with the heart at its centre and the limbs (left arm, right arm and legs) at the apices. This triangle forms the basis for the theory behind how the ECG functions.
What is the small squares on an ECG strip equal to?
One small box is 0.04 seconds. To get a heart rate, usually expressed as "per minute", divide 300 by the number of LARGE boxes between QRS wave peaks. A large box is 0.2 seconds. (Math: one minute = 60 seconds. One second = 5 x 0.2 seconds per large box, thus 60s x 5 boxes per second = 300 LARGE boxes per minute) which also happens to be the upper limit of normal for the PR interval used in determining the presence of primary AV block. One can also memorize the rate for the number of large boxes, rather than doing the math: 1 = 300; 2 = 150; 3 = 100; 4 = 75; 5 = 60. If you have more boxes than that, or less, you'd better page me rather than worrying about math!
What is the abbreviation for ecg lead v?
vertical
What is the difference between an MRI and a EEG?
Both measure electrical activity -- the ECG in the heart and the EEG in the brain.An EEG is an electroencephalogram and an ECG also known as an EKG is an electrocardiogram. An EEG records brainwave/electrical activity. An ECG records the electrical activity that the heart produces.
What is the name of the instrument that measures heartbeat?
An ECG (Electrocardiography) machine.
Which of the following procedures is abbreviated as either ECG or EKG?
An abbreviation for ElectroCardiogram: A procedure in which electrodes placed on the chest wall pick up the electrical conduction/activity of the heart. The depolarization and repolarization of the cardiac miocytes are are transcribed on a sheet of paper with the amplitude (+ or -) on the X axis, and time on the Y axis.
What is the vertical line on an ECG that indicates the pacemaker has discharged?
Pacer Spike otherwise known as (Pacemaker Spike)
What are the lines on paper that measure a heartbeat?
The ECG Tracings are seen on paper. The time intervals are shown as well as the measurements of each block on the paper.The ECG paper records time sequences (horizontal deflections) and amplitude (vertical deflections) of the electrical activity of the heart. The horizontal lines measure time intervals and heart rate.You will see first the P wave, the QRS complex, and the T wave. The P wave is the atria contracting, the QRS is the ventricle contacting, and the T wave is the relaxation of the ventricles.
What information does ecg gives about a person?
in an ecg test,the electrical impulses made while the heart is beating are recorded usually shown on a piece of paper.
What produces printed representations on ECG paper?
Know what happens in the P, QRS, and T complexes on an EEG?
What produces a printed representation on ECG paper?
Know what happens in the P, QRS, and T complexes on an EEG?
What is the Medical term meaning record of the heartbeat?
The medical term for a record of the heartbeat is electrocardiogram, commonly known as an ECG or EKG. This test measures the electrical activity of the heart and helps diagnose various heart conditions.
How can a heart murmur affect an ECG?
It won't. But in the long term the murmur (depending on which valve is affected) will cause hypertrophy of cardiac muscles for the different ventricles/atria. And the hypertrophy will be detected by the ECG because it will change the cardiac axis. Murmurs are easily heard using a stethoscope so and ECG isn't useful. An ECG monitors the electric impulses of the heart muscle - so better to see heart blocks, infarcts, hypertrophy, AF, SVT etc
What is the use of ECG?
The Electrocardiogram (ECG) is a diagnostic tool that is used to measure the regularity of heartbeats as well as the size and portion of the heart chambers and other heart related functions. The ECG also interprets the electrical activity of the heart over a period of time.
