Electronic Clinical Decision Support System for Stroke Risk Screening in Patients With Atrial Fibrillation in Mental Health Care: Mixed Methods Study

Electronic Clinical Decision Support System for Stroke Risk Screening in Patients With Atrial Fibrillation in Mental Health Care: Mixed Methods Study

AF is an arrhythmia characterized by irregular heartbeats. AF disrupts the ability of the heart to pump blood effectively, resulting in a higher risk of blood clotting within the left atrium of the heart and an increased risk of stroke [6].

Screening and Risk Analysis of Atrial Fibrillation After Radiotherapy for Breast Cancer: Protocol for the Cross-Sectional Cohort Study “Watch Your Heart (WATCH)”

Screening and Risk Analysis of Atrial Fibrillation After Radiotherapy for Breast Cancer: Protocol for the Cross-Sectional Cohort Study “Watch Your Heart (WATCH)”

AF is a common cardiac arrhythmia characterized by an irregular and often rapid heart rate [8,9] that can eventually lead to conditions with significant health impacts (stroke, heart failure, dementia) [10-12]. AF screening is challenging, further compounded by its frequent asymptomatic nature, which has often gone undetected in retrospective noninterventional studies.

Automated Process for Monitoring of Amiodarone Treatment: Development and Evaluation

Automated Process for Monitoring of Amiodarone Treatment: Development and Evaluation

Clinical background data were collected from patient records and stratified by the type of arrhythmia constituting indication for therapy. All patients received annual in-office appointments with a cardiologist for their clinical condition. Complementary follow-up with laboratory testing owing to the amiodarone treatment was carried out according to routine, irrespective of clinical follow-up.

Wearable Electrocardiogram Technology: Help or Hindrance to the Modern Doctor?

Wearable Electrocardiogram Technology: Help or Hindrance to the Modern Doctor?

This is particularly important, as the asymptomatic patient unaware of their arrhythmia will not present until serious sequelae (eg, stroke secondary to AF) occur. Furthermore, patients are often monitored for 24-48 hours, which has been shown to miss up to 30% of clinically significant arrhythmias [21]. Undoubtedly, consumer-owned smart technology negates many of these limitations. The question of efficacy remains.

Cancer and Atrial Fibrillation Comorbidities Among 25 Million Citizens in Shanghai, China: Medical Insurance Database Study

Cancer and Atrial Fibrillation Comorbidities Among 25 Million Citizens in Shanghai, China: Medical Insurance Database Study

Atrial fibrillation (AF) is the most prevalent arrhythmia and affects approximately 1% of the general population [1,2]. Besides its relation to cardiovascular complications and mortality, increased risk of various noncardiovascular diseases, including cancers, was evident in a population with AF [3]. Cancer is the leading cause of noncardiovascular deaths and is associated with increased major bleeding, intracranial hemorrhage, and arguably thromboembolic events in patients with AF [4-6].

The Australian Genetic Heart Disease Registry: Protocol for a Data Linkage Study

The Australian Genetic Heart Disease Registry: Protocol for a Data Linkage Study

Eligibility criteria include a confirmed diagnosis of any inherited cardiomyopathy (HCM, dilated cardiomyopathy, arrhythmogenic cardiomyopathy, and restrictive cardiomyopathy), left ventricular noncompaction, or primary arrhythmia syndromes (long QT syndrome, Brugada syndrome, or catecholaminergic polymorphic ventricular tachycardia; Table 1) or at-risk relatives of those with a confirmed diagnosis.

Corrected QT Interval (QTc) Diagnostic App for the Oncological Routine: Development Study

Corrected QT Interval (QTc) Diagnostic App for the Oncological Routine: Development Study

An increased QTc of 10 ms contributes to a 5% to 7% exponential increased risk to develop the life-threatening arrhythmia Td P. Thus, a QTc of 540 ms exposes the patient to a 63% to 97% higher Td P risk than a QTc of 440 ms, but there is no QTc value at which Td P certainly occurs [29-31]. In the case of drug-induced LQTS with a QTc increased to >500 ms or a QTc prolongation of >60 ms above the baseline, treatment discontinuation or alternative therapies should be considered [1].

Continuous mHealth Patch Monitoring for the Algorithm-Based Detection of Atrial Fibrillation: Feasibility and Diagnostic Accuracy Study

Continuous mHealth Patch Monitoring for the Algorithm-Based Detection of Atrial Fibrillation: Feasibility and Diagnostic Accuracy Study

A commercial arrhythmia analysis software (Awario, Heart2 Save) was used for automatic AF screening from the HRV data. The AI arrhythmia detection algorithm classified the HRV data in 30-second time windows into 3 categories: SR, AF, and uninterpretable. The accuracy of the AI-based rhythm classification from the HRV recording was further assessed by comparing it with the gold standard Holter ECG recording.
