Introduction. Atrial fibrillation is the most common sustained cardiac arrhythmia and is associated with a fivefold increase in risk of stroke.1 2 3 Treatment with anticoagulants reduces the risk by about two thirds.4 5 6 Non-valvular atrial fibrillation is categorised into three subtypes: paroxysmal if normal rhythm is restored spontaneously; …Atrial flutter is an arrhythmia that causes your heart to beat much faster than it should (around 300 beats per minute instead of the usual 60 to 100). Some people with atrial fibrillation have atrial flutter. If this is the case, you may get periods of atrial flutter followed by periods of atrial fibrillation.Atrial fibrillation (AF) is a common arrhythmia, with a lifetime risk exceeding 30% in individuals of European ancestry, and 20% in those of African ancestry. 1–4 Newly diagnosed AF may be triggered by acute, potentially reversible precipitants, including surgery, infection, acute myocardial infarction, and thyrotoxicosis, or it can …Atrial fibrillation (AF) is an ectopic rhythm originating in the atrium. An electrocardiogram (ECG) of AF shows the normal sinus P waves are replaced by f waves (350 to 600 beats per min) and the ventricular rate is often irregular, which is characterised by an uneven R-R interval. 1, 2 The prevalence of AF is higher in men than in women and it ...
They also noted that, if one does develop atrial fibrillation, tighter control may not further reduce their risk for possibly serious cardiovascular disease events. "Even after stringent blood pressure control to levels of less than 120/80 mmHg, the patients with atrial fibrillation have an 88 percent higher risk for poor outcomes," Parcha ...
Atrial fibrillation is a prevalent cardiac arrhythmia that poses significant health risks to patients. The use of non-invasive methods for AF detection, such as Electrocardiogram and Photoplethysmogram, has gained attention due to their accessibility and ease of use.

It includes guidance on providing the best care and treatment for people with atrial fibrillation, including assessing and managing risks of stroke and bleeding. The recommendations in this guideline were developed before the COVID-19 pandemic.
Cardiovascular Conditions. What Is Atrial Fibrillation? Normally, your heart contracts and relaxes to a regular beat. Certain cells in your heart, called the sinus node, make electrical signals that cause the heart to contract and pump blood. These electrical signals can be recorded using an electrocardiogram, or ECG.An AI-guided targeted screening approach that leverages existing clinical data increased the yield for atrial fibrillation detection and could improve the effectiveness of atrial ... Therefore, an HR needs to be interpreted as a weighted average effect during follow-up, and the absolute risks need to be provided to facilitate interpretation. ...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.Keywords: Atrial fibrillation, oral anticoagulation, stroke prevention.

These patterns can signify cardiac disease, such as left ventricular (LV) systolic dysfunction, silent atrial fibrillation (AF) and hypertrophic cardiomyopathy (HCM), but might also reflect systemic physiology, such as a person's age and sex or their serum potassium levels, as reviewed in detail herein.
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.

Amongst the group of patients aged between 55-74 years, the 10 year mortality was 61.5% in men with AF compared to 30% in men without AF. Amongst women in a similar age group, the 10 year mortality was 57.6% in the AF group versus 20.9% in women without AF. Similar findings have been found from many other cohorts.Atrial fibrillation can be interpreted by noting: an irregularly irregular rhythm and absent P waves A major complication associated with atrial fibrillation isRhythm control for the treatment of new‑onset atrial fibrillation after cardiothoracic surgery is current practice and amiodarone is most commonly used. This can still be considered, but there may be a reduction in the use of rhythm control in this population and an increase in the use of rate‑control drugs instead.Figure.

Hypertension is very common in AF patients (Figure S1 in the online-only Data ...In atrial fibrillation or atrial flutter, the atria do not empty completely into the ventricles with each beat. Over time, some blood inside the atria may stagnate, and blood clots may form. Pieces of the clot may break off, often shortly after atrial fibrillation converts back to normal rhythm—whether spontaneously or because of treatment.Findings: In 52 patients (male 69%, age 63 ± 9 yrs), QTc measured from Lead II correlated best with SR in majority of the formulae.
