The term "cardiac action" is used to describe the entire work performed by the heart. The main task of the heart is to pump blood through the vessels. We mainly use the term "cardiac action" to describe whether the heart beats rhythmically or arrhythmically (regularly or irregularly) and whether the heart beats too fast or too slow. If someone's heart beats regularly or evenly and just fast enough, we say that the cardiac action is rhythmic and normocardic.

Hay fever is a synonym for allergic rhinitis. Allergic rhinitis is an inflammation of the mucous membrane in the nasal cavity, usually caused by an allergy to pollen. The symptoms are very similar to those of a cold or runny nose (blocked nose, runny nose, sneezing), which is why it is also called hay fever.

HR is an acronym for heart rate. The normal heart rate or pulse for an adult is 60-100/min.

HSV is an acronym for herpes simplex virus. We know two types - HSV type 1 and HSV type 2. Herpes Simplex is a viral disease caused by two different viruses: Herpes Simplex Virus 1 (HSV-1) and Herpes Simplex Virus 2 (HSV-2). HSV-1 is the most common cause of oral herpes, which manifests as painful sores or blisters around the mouth. HSV-2, on the other hand, most often causes genital herpes, which manifests as painful sores in the genital area. The virus is transmitted through direct contact with the affected part of the body, either through kisses or sexual intercourse. Herpes cannot be cured, there are usually recurrent outbreaks. Herpes outbreaks can be treated with antiviral drugs.

Histamine intolerance is a condition that occurs when a large amount of histamine accumulates in the body. There are two reasons for the accumulation of histamine: excessive intake of histamine into the body or reduced breakdown of histamine. Symptoms of histamine intolerance are similar to those of an allergic reaction (headache, itching, swelling, difficulty breathing, etc.).

Histamine is a molecule that is produced in the human body and has numerous functions. It participates in the transmission of signals through the nervous system, is important in the function of the digestive system, is important in the inflammatory response, in allergic reactions, itching, etc. It also causes increased permeability of small vessels (capillaries). It is secreted by basophils and mast cells.

The term hypopigmentation refers to a patch on the skin that is lighter than its surroundings. Hypopigmentation can appear on the skin after inflammation, but it can also be part of other diseases (e.g. vitiligo).

It refers to a Latin term, which means hypodysplasia and hypofunction of the right kidney. The word hypofunction refers to reduced function. The word hypodysplasia refers to a smaller (typically congenital) kidney, with a reduced number of nephrons (the basic structural and functional unit in the kidneys), and the cells in the kidneys are also dysplastic (altered).

Herpetic infection is an infection with herpesviruses (usually by the phrase "herpetic infection" we mean HSV type 1 and HSV type 2. Herpes Simplex is a viral disease caused by two different viruses: Herpes Simplex Virus 1 (HSV-1) and Herpes Simplex Virus 2 (HSV-2). HSV-1 is the most common cause of oral herpes, which manifests as painful sores or blisters around the mouth. HSV-2 most commonly causes genital herpes, which manifests as painful sores in the genital area.
