Atrial fibrillation is associated with an increased risk of heart failure, dementia, and stroke. [3] [12] It is a type of supraventricular tachycardia. [14] Atrial fibrillation frequently results from bursts of tachycardia that originate in muscle bundles extending from the atrium to the pulmonary veins. [15]

Local feature extraction of P-wave or T-wave and frequency analysis of atrial fibrillation signals. Hilbert–Huang transform: Suitable for fully non-stationary and nonlinear signals. Provides instantaneous frequency distribution. Susceptible to mode mixing issues. Detection of transient heart rate variability.
An Apple Watch showing the numbers that track a typical run. A fitbit watch showing conditions for a workout A Garmin watch tracking activity and health data. Many devices primarily intended as smartwatches also function as fitness trackers. An early example was the Apple Watch, which has offered fitness tracker functions since 2014. [15]
Atrial fibrillation, an irregular heartbeat, is three times more common than previously thought, according to a new study published on Wednesday.. Estimates from more than two decades ago had ...
Atrial fibrillation may be due to serious underlying medical conditions and should be evaluated by a physician. It is not typically a medical emergency. It is not typically a medical emergency. Ventricular fibrillation occurs in the ventricles (lower chambers) of the heart; it is always a medical emergency.
The Apple Watch is a brand of smartwatch products developed and marketed by Apple.It incorporates fitness tracking, health-oriented capabilities, and wireless telecommunication, and integrates with watchOS and other Apple products and services.
In the context of atrial fibrillation, the Ashman phenomenon is a form of aberrancy. Aberrancy is due to prematurity in which part of the conduction system is still refractory and cannot conduct the premature depolarization. This effect can sometimes be seen in the setting of a faster heart rate (tachycardia) and so is termed "rate-related ...
