isoelectric lines!
Willem Einthoven invented the ECG in 1903. The letters P Q R S T were assigned to the points on the ECG because it was thought that there may be more points in either direction to be found. The letters remained in use out of common practice even after it was determined there were no further points to be labelled.
An isoelectric line on the electrocardiograph is the base line on an electrocardiogram.

The atrial repolarization occurs during the QRS complex of the ECG but is obscured by the ventricle depolarization.

S1Q3T3 is the classic finding but the EKG is usually nonspecific.
The result "nil acute" on an ECG test indicates that there are no signs of acute myocardial ischemia or infarction, meaning there are no immediate abnormalities that suggest a heart attack or other urgent cardiac issues. It suggests the heart's electrical activity appears normal at the time of the test. However, it is important to consider this result in conjunction with clinical symptoms and other diagnostic information. Always consult a healthcare professional for interpretation in the context of individual health.
A significant portion of Acute Coronary Syndrome patients have few ECG changes. They are diagnosed based largely on positive enzymes and those aggressively treated early have much better outcomes.
ECG stands for ElectroCardioGram
Never. An ECG is a test, not an illness or disease.
An ECG provides information about the wearer of the ECG's heartrate and rhythm of the heart. It provides information about wether it is normal or abnormal.
P wave corresponds to atrial depolarization in an ECG.
Electrocardiogram is also known as ECG or EKG
It can be tested with something called an ecg simulator.
ST segment elevation quite commonly occurs, but isn't a necessary requirement. Sometimes EKG changes are very subtle, or even nonexistent, initially.
The ECG sign of subendocardial ischemia is ST segment depression. Note that ECG is used more now that EKG.
