Heart arythmy
Arrhythmia of the heart (arrhythmia cordis; Greek arrhythmia - irregularity, lack of rhythm, a- - negative frequency + rhythmos - rhythm) is a name that unites disturbances in the formation of an impulse of excitation or its conduction through the myocardium; manifested by disturbances in the rhythm of heart contractions.
The following types of cardiac arrhythmias are distinguished:
- Respiratory (respiratoria; synonym: Hering phenomenon) - an increase in heart rate during inhalation and its decrease during exhalation; caused by a change in the tone of the vagus nerve, is a type of sinus arrhythmia;
- Atrial fibrillation (fibrillaris; synonyms: complete arrhythmia, (outdated) "delirium") - atrial fibrillation with complete irregularity of breaks between heartbeats, and the force of contractions of the ventricles of the heart;
- Atrial bradystolic (fibrillaris bradysystolica; synonym: atrial bradyarrhythmia) - occurs with no pulse deficit and reduced or normal heart rate;
- Atrial fibrillation - characterized by the presence of relatively rare and large teeth of atrial fibrillation on the ECG;
- Atrial fibrillation - characterized by the presence of relatively small and frequent waves of atrial fibrillation on the ECG;
- Atrial paroxysmal (fibrillaris paroxysmalis) - characterized by paroxysmal course; in the intervals between attacks, the correct sinus rhythm is noted;
- Atrial fibrillation (fibrillaris perpetua) - characterized by constant atrial fibrillation; usually occurs due to overload or organic lesions of the atria;
- Atrial tachysystolic (fibrillaris tachysystolica; synonym: atrial tachyarrhythmia) - is characterized by increased heart rate and is accompanied by a pulse deficit;
- Atrial fibrillation (fibrillaris eurhythmica) - the frequency of ventricular contractions is within the limits that are normal for a healthy person;
- Paroxysmal (paroxysmalis) - arises and stops suddenly, proceeds against the background of a normal nomotopic heart rhythm or a relatively constant form of heart rhythm disturbance of a different nature;
- Post-conversion (Latin prefix post- - after + conversio - circulation) - is observed after restoration of sinus rhythm in patients with atrial fibrillation, paroxysmal tachycardia or atrial flutter;
- Sinus (sinuosa) - due to fluctuations in the automatic activity of the sinus-atrial node, usually associated with fluctuations in the tone of the vagus nerve.
