1. Introduction. Atrial fibrillation (AF) is associated with not only increased morbidity and mortality but also with impaired health-related quality of life (QoL) , .Furthermore, maintenance of sinus rhythm alleviates symptoms and improves QoL in patients with paroxysmal and persistent AF , .Impaired QoL might, however, in the context of AF be due to several factors including sex, severity of ...Atrial fibrillation is generally considered a tachyarrhythmia, (an arrhythmia with a heart rate of more than 100 beats per minute). Patients experiencing atrial fibrillation generally have the following characteristics: P waves are absent. The QRS complex is narrow (less than 0.12 seconds) The R-R intervals are consistently irregular.The most common arrhythmia at admission was atrial fibrillation (68%), followed by atrial flutter (16%) and reentrant tachycardia (16%). The results of the first determination of hs-cTnT were positive (> 14 ng/l) in 44.2% of the patients and the second determination, separated by 3 hours, was positive in 50.7% of the cases. ...Atrial rhythms originate in the atria rather than in the SA node. The P wave is positive, but its shape can be different from a normal sinus rhythm because the electrical impulse follows a different path to the AV (atrioventricular) node. Common atrial arrhythmias include premature atrial contractions, atrial fibrillation, and atrial flutter.The RATE-AF trial, published in 2020, demonstrated the effectiveness of low dose digoxin for atrial fibrillation . The randomized trial included 160 patients with chronic atrial fibrillation. The mean age of study participants was 76 years, 46% were female, and classified as New York Heart Association Class II or above.

Atrial Fibrillation (Afib) Atrial fibrillation (Afib) is an irregular heart rhythm that begins in your heart’s upper chambers (atria). Symptoms include fatigue, heart palpitations, trouble breathing and dizziness. Afib is one of the most common arrhythmias. Risk factors include high blood pressure, coronary artery disease and having obesity.An ECG signal represents the electrical activity of the four chambers of the heart. This signal is a series of a P wave, QRS complex, and a T wave as shown in Figure 1. Figure 1. Normal electrocardiogram (ECG) signal with wave durations and intervals. The P wave indicates atrial depolarization.The cornerstones of atrial fibrillation (AF) management are rate control and anticoagulation [1, 19] and rhythm control for those symptomatically limited by AF.

The patient with newly diagnosed atrial fibrillation. The NHFA’s AF guidelines recommend opportunistic AF screening in patients aged ≥65 years with either radial pulse palpation followed by a 12-lead electrocardiogram (ECG) or a single-lead handheld ECG. 9 Therefore, AF can be diagnosed: during routine cardiac screening.Introduction. Atrial fibrillation is a common supraventricular arrhythmia with increased risk of stroke and heart failure [].Atrial fibrillation is most often diagnosed by an irregular rhythm and absent P waves (or rapid irregular fibrillatory waves) on the 12-lead ECG [].Regarding anticoagulant therapy, atrial flutter is managed the same way as …The QT interval on the electrocardiogram (ECG) has gained clinical importance, primarily because prolongation of this interval can predispose to a potentially fatal ventricular arrhythmia known as torsades de pointes. Multiple factors have been implicated in causing QT prolongation and torsades de pointes.Atrial fibrillation (AF) can manifest in a broad range of acute medical and surgical conditions. Although previously postulated as transient and isolated events, accumulating evidence suggests that AF detected in the setting of acute care or acute illness is associated with a high risk of long-term AF recurrence, 1–15 warranting …Atrial fibrillation (AF) is an arrhythmia that can occur as the result of numerous different pathophysiological processes in the atria. Some aspects of the morphological and electrophysiological alterations promoting AF have been studied extensively in animal models. Atrial tachycardia or AF itself shortens atrial refractoriness and causes loss of …Atrial fibrillation also may impair cardiac output; loss of atrial contraction can lower cardiac output at normal heart rate by about 10%. Such a decrease is usually well tolerated except when the ventricular rate becomes too fast (eg, > 140 beats/minute), or when patients have borderline or low cardiac output to begin with.Atrial fibrillation or flutter. Atrial fibrillation (Afib) and atrial flutter are common types of abnormal heart rhythms (arrhythmias) which affect the upper chambers (atria) of the heart. In atrial flutter, the heart beats too fast, but mostly continues to contract in a regular rhythm. AFib is a closely related condition in which the atria ...Atrial fibrillation is the most common form of heart arrhythmia in the world. It is currently estimated that between 2.1 and 6.7 million Americans are currently living with atrial fibrillation, with the number trending upwards every year. Trending.

Atrial fibrillation is the most common pathologic tachyarrhythmia (only sinus tachycardia is more common). Prevalence of atrial fibrillation correlates strongly with age. Approximately 10% of individuals aged 80 years and above have atrial fibrillation, whereas the arrhythmia is unusual among persons younger than 50 years of age.

When a patient experiences A-fib, the atria are not contracting as they normally would. They are just quivering. This absence of contraction of the atria can …

However, atrial fibrillation can lead to other serious complications, so it needs to be treated promptly and monitored closely. During atrial fibrillation, the heart's two upper chambers (atria) beat chaotically and irregularly, out of coordination with the two lower chambers (ventricles). Because of the uncoordinated heartbeat it produces ...Atrial fibrillation (AF), the most common sustained arrhythmia, is a leading cause of stroke, and is associated with significant morbidity and mortality worldwide. ... These results, however, must be interpreted with caution given the small sample sizes and the highly variable criteria for defining CFAEs which limits the ability to combine the ...The risk of atrial fibrillation increases with age because the risk for heart disease and other conditions that can cause atrial fibrillation also increase with age.
