Synonyms in the broadest sense Cardiac arrhythmias Arrhythmia Tachycardia Bradycardia Atrial fibrillation Atrial flutter Extrasystoles Sick Sinus Syndrome AV Block Supraventricular dysrhythmia Ventricular dysrhythmia Definition A cardiac dysrhythmia (also called arrhythmia, “unrhythmic”) is a disturbance of the normal heartbeat sequence, caused by abnormal processes in the formation and conduction of excitation in the heart muscle. … Cardiac arrhythmia

BasicsPhysiology of the heart The heart rhythm is the temporal sequence of contractions of the “pumping organ” heart. A regular rhythm of the heart‘s actions ensures the heart’s efficiency. A “heartbeat” actually consists of two contractions in quick succession (contraction of the heart muscle), that of the atrium and the subsequent contraction of the ventricle. … BasicsPhysiology of the heart | Cardiac arrhythmia

Classification of cardiac arrhythmias In bradycardia, the heart beats slowly and the pulse is less than 60 beats per minute. Bradycardia is often observed in competitive athletes without being pathological. The two most important cardiac dysrhythmias associated with bradycardia Bradycardia = In tachycardia the heart beats unusually fast, the pulse is over 100 beats per … Classification of cardiac arrhythmias | Cardiac arrhythmia

Certain rhythm disturbances In the following, the individual rhythm disturbances are described in more detail and explained how they arise and with which symptoms they are associated. The most important instrument for diagnosing cardiac arrhythmias is the ECG (electrocardiography). Various cardiac arrhythmias lead to characteristic changes in the ECG. These are also described here. Unfortunately, … Certain rhythm disturbances | Cardiac arrhythmia

Beta blocker Beta-blockers are drugs that are able to block certain receptors, so-called ?-receptors (beta-receptors) in the human body and thus prevent the effect of the stress hormones adrenalin/noradrenalin on these receptors. Preferably, they are used in so-called tachycardic cardiac arrhythmias, as rhythm disturbances in which the heart beats with too many beats per minute. … Beta blocker | Cardiac arrhythmia

Symptoms of cardiac dysrhythmia The symptoms of cardiac arrhythmias can be as varied as there are different types of arrhythmias. As a rule, they occur with changes in the beat frequency >160/min and <40/min and with all beat irregularities that lead to disturbances in the cardiovascular system. In some cases they can occur completely without … Symptoms of cardiac dysrhythmia | Cardiac arrhythmia

Cardiac arrhythmia in children In principle, all types of cardiac dysrhythmia that occur in adults can also be present in children. In most cases, however, these are not acquired, as in adults, but are congenital cardiac dysrhythmias from the beginning (e.g. due to congenital heart defects, heart valve defects, heart muscle diseases, etc.). In some … Cardiac arrhythmia in children | Cardiac arrhythmia

Cardiac arrhythmia and thyroid gland The thyroid gland can always cause cardiac arrhythmia when it is overactive and produces too many thyroid hormones, resulting in an oversupply of these in the blood system (hyperthyroidism). A benign lump in the thyroid tissue also leads to hyperthyroidism. This also affects the function of the heart. This is … Cardiac arrhythmia and thyroid gland | Cardiac arrhythmia
