• High blood pressure is defined by a too high pressure rise in the arteries, which persists while the subject is at rest. To talk about Hypertension, you need: An increase in systolic blood pressure to 14 cmHg (140 mmHg) or more; Or a rise in diastolic blood pressure to 9 cmHg (90 mmHg) or more.

​

​

• Blood pressure can be measured and expressed in millimeters of mercury (mmHg) or centimeters of mercury (cmHg). When the heart contracts, it acts as a pump that propels the blood in all the arteries to bring energy and oxygen to the body. The blood, thus circulated, exerts pressure on the walls of the arteries.

​

• The cardiac arrhythmia corresponds to a disturbance of the cardiac rhythm that is to say a disturbance of the cardiac rhythm which can be benign or require a suitable treatment.

​

​

• Cardiopulmonary arrest or cardio-ventilatory arrest, more commonly known as cardiac arrest, but also sudden death of the adult can be caused by myocardial infarction, trauma, asphyxiation, drowning, hypothermia or electrocution. The affected person loses consciousness immediately and stops breathing or has slow, noisy and anarchic breathing movements.

​

• The cardiologist is the doctor who specializes in the prevention, diagnosis and treatment of diseases of the heart and vessels. The cardiologist is called upon to consult a patient in case of chest pain, shortness of breath, syncope or palpitations. Cardiology studies heart rhythm disorders, venous and vascular diseases, in adults and children.

​

​

• Myocardial infarction, or heart attack in everyday language, is a death of the heart cells due to a lack of vascularization and thus oxygenation of these cells. Generally, an infarction is due to a clot or deposits on the wall that blocks a coronary artery. The heart acts as a "pump" within the body. It propels the blood through the body and therefore plays a driving role in the bloodstream. During a myocardial infarction, certain branches of the main arteries of the heart called coronary clog up. The blood does not pass and some of the heart muscle tissue "dies".

​

​

• The heartbeat or heart rate refers to the pulsation of the heart to irrigate the entire human body with blood. The number of beats per minute allows to establish, via the pulse, the heart rate (70 on average in humans).

​

​

• An electrocardiogram (ECG) is the examination that allows the recording of the heart rhythm. The ECG consists of precisely studying the activity of the heart, thanks to electrodes placed on the chest, wrists and ankles. This activity is measured at several points in the heart, called derivations, and is recorded as a curve for each of them.

​

​

• Fibrillation is a term for disordered contractions of the heart muscle by desynchronization between the different cavities of the heart. The auricular is distinguished when it reaches the auricles, and the ventricular fibrillation when it comes to the ventricles at the origin of this disorganization.

​

• Blood glucose is the plasma concentration of glucose. During the day, its value varies according to the contributions and energy needs of the individual. The blood glucose is adjusted by the action of hormones secreted by pancreatic cells. It is evaluated fasting and is normally between 0.70 and 1.10 grams of glucose per liter of blood.

​

​

• Hypoglycemia is the reduction of the amount of glucose, the main energy source, in the blood. Hypoglycemia is referred to as 0.50 g of glucose per liter of blood.

​

​

• Hyperglycemia is a disorder that is manifested by an abnormal rise in blood sugar. Hyperglycemia is referred to as 1.26 grams of glucose per liter of blood.

​

​

• An ultrasound is a wave, of the same nature as sound waves, but whose frequency range is between 20 kilohertz and several hundred megahertz.

​

​

• Contractions during pregnancy are spasms of the uterus that harden the belly.

​

​

• The pain is considered chronic when it exceeds three months and becomes recurrent beyond. Chronic pain is a disease, as opposed to the acute pain that is a symptom.

​

​

• Venous return is referred to as the blood circulation stage where oxygen depleted blood, located in the lower limbs, is sent up the body to regain oxygen.

​

​

• The feeling of heavy legs is linked to a poor circulation of blood in the veins. It is sometimes accompanied by cramps, tingling or edema.
