Sometimes the patient may experience both flutter and atrial fibrillation: these are quite serious cases, which require special attention from doctors. This is an extremely important detail, as it is often the case that the flutter goes unnoticed for this very reason. In fact, flutter is distinguished as 2:1, 3:1 or 4:1, indicating that only one out of every 2, 3 or 4 stimuli manages to pass through the block. Generally speaking, during these arrhythmias, a blockage is established at the level of the atrioventricular node, which stops part of the impulses directed towards the ventricle this occurs particularly during atrial flutter, so much so that in subjects affected by this condition, the ventricular contraction can be as much as ¼ of the atrial contraction. This also means that, compared to fibrillation, the beat is less disordered, as a reduced frequency results in fewer contraction impulses. The characteristics of atrial flutter are similar to those of atrial fibrillation, but flutter differs from the latter in that the changes in the heartbeat are less pronounced and have a different impact on the ventricles: in fact, while atrial fibrillation can lead to an increase in the heartbeat of up to 400 bpm, during a flutter the heartbeat rate can rise to a maximum of 240-300 bpm. Atrial flutter and atrial fibrillation: characteristics and differences Specific targeted therapy is usually required to treat this condition. However, in this case the disorder may last for years and be synonymous with an associated pathology due to its latent nature, the diagnosis of atrial flutter is often not immediate and the condition may go undetected. Permanent atrial flutter: In the permanent form, the development of the disorder is often gradual. This type of disorder affects healthy individuals, who may experience isolated attacks, and therefore does not usually require drugs or other therapeutic interventions. The heart rate of a patient suffering from atrial flutter can be as high as 120/180 beats per minute, but the episodes usually end within a few hours, or a few days at most. Paroxysmal atrial flutter: the paroxysmal form is characterised by a sudden onset of attacks, which are usually of short duration. Two forms of atrial flutter can be distinguished: a paroxysmal form and a permanent form What is atrial flutter?Ītrial flutter is an alteration in cardiac rhythm that originates in the atrium and can spread to the ventricle, affecting cardiac output and blood circulation given its area of onset, it is classified as an ectopic supraventricular arrhythmia.Įpisodes of atrial flutter are characterised by an irregular heartbeat with frequent contractions and accelerated pulsations flutter means ‘rapid heartbeat’, and patients affected by this condition may have a heart rate of more than 200 beats per minute (bpm). Its treatment may vary from patient to patient. The diagnosis of atrial flutter is based on a thorough cardiological examination that includes an electrocardiogram. The causes of the disorder may be physiological in nature, may be due to underlying pathologies or may depend on external factors. Depending on the mode of onset, two forms of atrial flutter can be distinguished: a paroxysmal form, with abrupt, short-lasting episodes, and a permanent form Atrial flutter is a cardiac arrhythmia that can occur in the atria, characterised by frequent contractions, irregular heartbeat and sudden onset.
