Medical News Today: How does a doctor diagnose atrial fibrillation?

Atrial fibrillation creates an irregular heart rhythm called arrhythmia. A doctor can use physical examination and machine testing to diagnose and treat this common heart disorder. Read on to learn more.

In this study, we elaborate on a tentative interpretation of the observed intermittent dynamics during AF as the signature of synaptic plasticity. Typical individual GJC transition times between open and closed states were shown to be much longer than those of membrane polarization but compare well with membrane recovery time (≳ 100ms) (Spray et al., 1984; Neyton and Trautmann, 1986; Wang et al., 1992; Bukauskas and Verselis, 2004; Desplantez et al., 2007). Moreover, slow gating modulations have been evidenced due to cytoplasmic protons (low pH) and free calcium (Spray et al., 1984; Burt and Sray, 1988; Kumar and Gilula,...

Conclusions: Embolism associated with asymptomatic carotid stenosis shows circadian variation with highest rates 4–6 h before midday. This corresponds with peak circadian incidence of stroke and other vascular complications. These and ASED Study results show that monitoring frequency, duration, and time of day are important in ES detection. Introduction Transcranial Doppler (TCD) detected microembolism in the ipsilateral middle cerebral artery (MCA) may help stratify the risk of stroke and other arterial disease complications in persons with advanced (≥60%) asymptomatic carotid stenosis. If so, this techniqu...

Abstract BACKGROUND: Chronic hepatitis C virus (HCV) infection is associated with higher risk of cardiovascular events than chronic hepatitis B virus (HBV). We aimed to investigate whether there is higher risk of arrhythmia in HCV infection. METHODS: Electronic medical records from National Health Institute Research Database during 2000-2012 were retrieved for patients with HBV or HCV. Patients with missing information, aged

We report the results of first repeat AF ablation procedures of aged patients from a real-world multicenter prospective registry.MethodsPatients undergoing second AF ablation included in the prospective, multicenter German Ablation Registry were divided in two groups (age>  70 years (group 1) and age ≤ 70 years (group 2)) and analyzed for procedural characteristics and clinical follow-up.Results738 patients were analyzed (108 patients in group 1, 630 patients in group 2). Significantly more aged patients had structural heart disease (56 patients (51.9%) vs. 203 patients (32.2%),p

san M Abstract Over the past three decades, the increasing rates of obesity have led to an alarming obesity epidemic worldwide. Obesity is associated with an increased risk of cardiovascular diseases; thus, it is essential to define the molecular mechanisms by which obesity affects heart function. Individuals with obesity and overweight have shown changes in cardiac structure and function, leading to cardiomyopathy, hypertrophy, atrial fibrillation, and arrhythmia. Autophagy is a highly conserved recycling mechanism that delivers proteins and damaged organelles to lysosomes for degradation. In the hearts of patien...

Abstract BACKGROUND: Pulmonary vein isolation (PVI) is an accepted strategy for paroxysmal atrial fibrillation (PAF) and persistent AF (PerAF) ablation. Limited data are available on outcomes of cryoballoon (CB) PVI in patients with structural heart disease (SHD). The purpose is to assess the clinical efficacy of a single CB-PVI procedure in patients with PAF or PerAF who also have SHD. METHODS: From April 2012, 460 AF patients with concomitant SHD underwent CB-PVI and were followed prospectively in the framework of the 1STOP ClinicalService® project. Data on procedural outcomes and long-term freedom from...

AbstractPurposeAtrial fibrillation (AF) is a frequently encountered cardiac arrhythmia in clinical practice. While fried food consumption is common in United States, little is known about the association between fried food consumption and incident AF.MethodsWe prospectively examined the association of fried food consumption with incident AF in 18,941 US male physicians. Fried food consumption was assessed via a self-administered food frequency questionnaire. Incident AF was ascertained through yearly follow-up questionnaires. Cox regression was used to estimate relative risks of AF.ResultsThe average age at baseline was 66...

Sound, rhythm, rate, structure, function – countless features of the heart are measured to keep it healthy for as long as possible. Recently, an army of digital health technologies joined the forces of traditional preventive tools in cardiology to counter stroke, heart attack, heart failure or any other cardiovascular risks. In the future, minuscule sensors, digital twins, and artificial intelligence could strengthen their ranks. Let’s see what the future of cardiology might look like! Fitness trackers, chatbots and A.I. against heart disease Let’s say 36-year-old Maria living in Sao Paulo in 2033 d...

Arrhythmias are common in horses. Sinus arrhythmia and first- and second-degree atrioventricular block are frequently found physiologic arrhythmias, but should immediately disappear after stress or exercise. Atrial premature depolarizations are usually not associated with poor performance, but are a potential trigger for atrial fibrillation. Atrial fibrillation results in an abnormal ventricular response during exercise and poses a risk for collapse in some horses. This arrhythmia can usually be treated by quinidine sulfate or transvenous electrical cardioversion. Ventricular premature depolarizations, especially when asso...
