In cardiology, what are the waves?
When the heart muscle alternately withdraws and relaxes to the pumping of blood, the electric nervous waves that create these contractions spread throughout the body. This creates a characteristic formula that can be measured by electrocardiogram (ECG) when it is recorded from wires located on a trunk or limbs. The T wave shows an electric wave accompanying the relaxation of the chambers, two large petrol chambers at the bottom of the heart.
doctors can look for changes in the wave T, which is the most popular of the different waves of the ECG measured to find out potential patient heart problems or general health. Abnormalities in the t wave can simply reflect the advanced age of the patient, but many other conditions cause T waves disorders. Damage in the heart valve area, reduced blood flow in the heart and heart attacks can cause t waves.
Inflammation or surrounding hearts such as myocarditis or pericarditis, so can Alpine to distort t waves. Doctors will also notice changes in the wave t after the bruising of the chest with the bruises orbleeding around the heart. Finally, some problems with the central nervous system, especially bleeding into the lining membrane of the brain, cause a longer interval between the waves of QRS and T waves called a long QT interval.
When doctors see flattened or inverted t waves, they may suspect poor blood flow to the heart. This may also happen when the left ventricle increases due to permanent high blood pressure or atherosclerosis. This effect can also be caused by digoxin, a common heart remedy. Abnormally high t waves can be the first sign of myocardial infarction or heart attack.
The QT interval is an example of the time for both electric waves that cause heart contraction and release. On average, the QT interval lasts from 0.2 to 0.4 seconds. The prolonged QT interval can reveal some unusually fast heart rhythms called tachyarthmia, which may lead to sudden death while a short Qt interval can indicateWatch high calcium levels in the blood. The ST segment, which is the distance to the ECG from the wool with the wool QRS to the top of the T wave, shows the length of time between the maximum contraction of the chambers and the beginning of its relaxation. In cases of poor ventricular blood flow, ST segments may increase or depressed.
