Also called Ocular hypertension or increased intraocular pressure is when the pressure inside the eye (intraocular pressure or IOP) is higher than normal. If it stays high or continues to increase, it exerts a force within the eye's interior that can damage the eye's delicate optic nerve, causing glaucoma.
Intraocular pressure is caused by the fluid inside the eye (aqueous humour) mainly determined by the coupling of its production and the drainage. Normal eye pressure ranges from 10 to 21 mm. 

Electrocardiogram (Elektro-kardiographie) is a test that checks for problems with the electrical activity of the heart. Devices record the heart's electrical activity as line tracings with spikes and dips (waves)  - traditionally on paper, but also digitally. 

The heart is a muscular pump made up of four chambers . The two upper chambers are called atria. The two lower chambers are called ventricles. The first upward pulse of the EKG signal, the P wave, is formed when the atria contracts to pump blood into the ventricles. In Atrial Fibrilation there will be many “fibrillation” beats instead of one P wave. The next large upward spike segment, the QRS Complex, is formed when the ventricles are contracting to pump out blood. Main Features to Consider are its width (too narrow means Supraventricular tachycardia (SVT) arising from improper electrical activity of the heart., too broad - could mean hyperkalaemia or sodium-channel blockade), height (voltage) and specific shape. The ST segment, measures the end of the contraction of the ventricles to the beginning of the rest period before the ventricles begin to contract for the next beat..The T wave, measures the resting.

The accuracy of the ECG depends on the condition being tested. A heart problem may not always show up on the ECG. Many medicines can change the results of this test.
​
An EKG is done to:

• Check the heart's electrical activity and examine other possible abnormalities  - e.g. in the walls of the heart chambers
• Find the cause of unexplained chest pain or pressure. 
• Find the cause of shortness of breath, dizziness, fainting, and palpitations (rapid or irregular heartbeats), high blood pressure, and other conditions

Esophagogastroduodenoscopy (EGD) is a diagnostic endoscopic procedure that visualizes the upper part of the gastrointestinal tract up to the duodenum. It is considered a minimally invasive procedure since it does not require an incision into one of the major body cavities and does not require any significant recovery after the procedure (unless sedation or anesthesia has been used). However, a sore throat is common

ethyl alcohol, also known as grain alcohol (absolute alcohol if undiluted), is the principal type of alcohol found in alcoholic beverages. This compound with molecular formula C2H5OH has a very distinctive perfume-like smell. It is produced by the fermentation of sugars by yeasts, most notably, Saccharomyces cerevisiae. 

Ethanol can be measured in breath (30 minutes after consumption), sweat (over 40 minutes after consumption) and blood. The presence of ethanol in blood at concentrations >30 mg/dL (>0.03% or g/dL) is generally accepted as a strong indicator of the use of an alcohol-containing beverage. Ethanol can be also detected in high amounts in the blood of those with auto-brewery syndrome (gut fermentation syndrome) or smaller but still elevated amounts with yeast or bacterial dysbiosis (overgrowth) through endogenous fermentation within the digestive system.
