"Hemiblock" Natural Recordings by Native Speakers
Hemiblock is an irregular heart rhythm characterized by a blockage of electrical signals in the heart, typically occurring in the right bundle branch. It impairs the heart's ability to pump blood efficiently, often causing symptoms such as rapid or irregular heartbeat, shortness of breath, fatigue, and dizziness.
Hemiaplasia is a medical term that refers to the condition where there is an absolute absence or underdevelopment of half of a limb or digit. It is a type of congenital anomaly, meaning it is present at birth. In individuals with hemiaplasia, the affected limb is typically smaller than the normal counterpart and may be absence of certain muscles, bones, or other structures. This condition can occur on either the upper or lower extremities, and the severity of the condition can vary widely from individual to individual.
Hemiascomycetes is a class of fungi in the subphylum Pezizomycotina. It includes yeasts, which are single-celled fungi that can reproduce by budding or fission. The term "Hemiascomycetes" comes from the Greek words "hemi" meaning "half" and "skomos" meaning "ashen", referring to the typically ashy appearance of the fruiting bodies of some members of this group.
Hemibalism is a rare neurological disorder characterized by a tendency to favor one side of the body, but not as extreme as hemiparesis (weakness on one side) or hemiplegia (paralysis on one side). People with hemibalism may exhibit involuntary movements, incoordination, and difficulties with balance and spatial awareness.
Hemiballism is a rare neurological disorder characterized by abnormal involuntary movements, specifically tremors and chorea (involuntary jerky movements), predominantly affecting one side of the body. The term "hemiballism" literally means "half-ballism", with "hemi-" referring to half and "ballism" referring to the sudden, jerky movements of the affected limbs.
Hemicardia refers to a rare heart disorder characterized by an irregular, wandering loss of atrioventricular (AV) conduction. It is a type of atrioventricular block, where the electrical impulses that regulate the heartbeat (from the atria to the ventricles) become blocked or interrupted. This blockage can lead to palpitations, arrhythmias, and even complete heart failure if left untreated.
Hemicellulose is a type of complex carbohydrate found in the cell walls of plants. It is a straight-chain polysaccharide made up of five-carbon sugars, such as arabinose, xylose, and glucose, that are linked together through beta-1,4 glycosidic bonds. Hemicellulose is broken down into smaller sugars by enzymes during the digestion process in the rumen of ruminant animals, such as cows and sheep, and is an important source of energy for these animals. It is also used in the production of biofuels, paper, and other products.
