Synonyms in the broadest sense Tachycardia absoluta Tachyarrhythmia absolute Tachycardia Heart Chase Atrial flutter or fibrillation is a temporary (intermittent or paroxymal) or permanent (permanent) arrhythmia with disordered activity of the atria. In atrial flutter, the atria contract at frequencies of more than 250-350 beats per minute. In atrial fibrillation, frequencies of 350 to 600 … Atrial flutter and atrial fibrillation
General causes Atrial flutter/flicker can occur in all diseases of the heart that are associated with damage or overstretching of the atria. Diseases that often lead to atrial fibrillation: Multiple reentry circuits are considered the basic mechanism of atrial flutter/flicker. During normal cardiac action, any potential is lost once the ventricular muscles are reached, as … General causes | Atrial flutter and atrial fibrillation
Consequences As a consequence of atrial fibrillation, a decrease in cardiac output may occur because the atria with their pumping function no longer contribute to filling the chambers. In addition, a permanent ventricular tachycardia due to conduction via the AV node can lead to damage of the ventricular muscles, which can lead to heart failure … Consequences | Atrial flutter and atrial fibrillation
Treatment of atrial fibrillation In the treatment of atrial flutter, not only the age of the patient but also secondary diseases are taken into account. In young patients who do not have any significant concomitant diseases, an attempt is first made to normalize the corresponding point in the stimulus transmission system, which generates irregular impulses, … Treatment of atrial fibrillation | Atrial flutter and atrial fibrillation
Prognosis The prognosis is strongly dependent on the underlying disease. There are no significant prognostic differences between the application of the individual therapy forms (frequency or rhythm control). All articles in this series: Atrial flutter and atrial fibrillation General causes Consequences Treatment of atrial fibrillation Prognosis
Therapy of atrial fibrillation and atrial flutter If possible, a causal therapy of the atrial fibrillation should be aimed at, which treats the underlying disease. Atrial fibrillation that occurs acutely usually disappears spontaneously after initiation of therapy. If it remains, a decision must be made between two equivalent therapy concepts: Frequency control and rhythm control. … Atrial fibrillation therapy
Drugs Drug treatment of atrial fibrillation depends on the cause. In addition, the drugs, known as antiarrhythmics, have clear indications, contraindications and interactions with other drugs. Commonly used drugs in atrial fibrillation are beta blockers, flecainide, propafenone and amiodarone. Beta-blockers such as bisoprolol are drugs that act on the so-called beta-adrenoreceptors. They are used to … Drugs | Atrial fibrillation therapy
What is a cardioversion? The term cardioversion describes the restoration of a normal heart rhythm (so-called sinus rhythm) in the presence of cardiac arrhythmias such as atrial fibrillation. There are two different methods of restoring a normal heart rhythm by means of cardioversion: electrical cardioversion by means of a defibrillator, also known as electric shock, … What is a cardioversion? | Atrial fibrillation therapy
Pacemaker Pacemakers are used, for example, to treat a slow heart rate or atrial fibrillation. The pacemaker provides the heart with regular electrical stimulation, which prevents the occurrence of atrial fibrillation. Whether a pacemaker is necessary depends on the cause of the atrial fibrillation. Ablation Cardiac ablation is a treatment in which surplus or diseased … Pacemaker | Atrial fibrillation therapy
Guidelines for the treatment of atrial fibrillation The guidelines of the German Society of Cardiology (DGK) provide guidelines for the treatment of atrial fibrillation. To diagnose suspected but undocumented atrial fibrillation, cardiac rhythm monitoring may be necessary to determine the type of atrial fibrillation. In the chronic condition called atrial fibrillation, there are different types … Guidelines for the treatment of atrial fibrillation | Atrial fibrillation therapy
