Summary
Mobile ECG screening for atrial fibrillation (AF) in primary care detected the condition in 6.2% of older patients. The KardiaMobile device showed high physician acceptance and ease of integration, suggesting its effectiveness for widespread AF detection.
Area of Science:
- Cardiology
- Digital Health
- Primary Care Medicine
Background:
- Atrial fibrillation (AF) is a significant stroke risk factor, affecting 1-4% of the population.
- Novel AF screening technologies require real-world clinical validation.
- Undiagnosed AF is prevalent in older adults seeking primary care.
Purpose of the Study:
- To assess the introduction and feasibility of a mobile electrocardiogram (ECG) device for AF screening.
- To evaluate the device's performance in a large, unselected primary care population.
- To gauge physician acceptance and perceived clinical value of the mobile ECG technology.
Main Methods:
- 184 Canadian primary care physicians received KardiaMobile ECG devices for 3 months.
- Physicians screened patients aged ≥65 without prior AF diagnosis.
- Physician feedback was collected via Likert scale questionnaires.
Main Results:
- 133 physicians (72%) participated, screening 7585 patients.
- Newly diagnosed AF was found in 471 patients (6.2%).
- Physicians reported high clinical value (94%) and ease of integration (89%).
Conclusions:
- Undiagnosed AF is common in older primary care patients.
- The KardiaMobile ECG device is an effective AF screening tool with high physician acceptance.
- Further research is needed to integrate novel screening technologies into population-based programs.

03:03Amyloid Fibrils
11.7K
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...

01:29Electrocardiogram
5.6K
An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.

Introduction
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.

3.2K
Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...
