Atrial fibrillation is a very common clinical arrhythmia, and the overall incidence of the population is about 1%. And the incidence of atrial fibrillation gradually increases with age. Among the 40-50 years old population, the incidence of atrial fibrillation is about 0.5%; and among the elderly over 80 years old, the incidence of atrial fibrillation Up to 8%-10%. According to the calculation of the global population of 6 billion, there are about 60 million patients with atrial fibrillation.
The typical symptoms of patients with atrial fibrillation are palpitations, and even chest pain and even heart failure due to myocardial ischemia induced by rapid heart rate. However, many patients have asymptomatic atrial fibrillation, especially patients with paroxysmal atrial fibrillation. Intermittent atrial fibrillation did not bring any complaints, but the absence of symptoms does not mean that there is no harm. These patients often have stroke as the first symptom. There are also patients with enlarged heart and cardiac insufficiency at the time of discovery.
Therefore, timely detection of atrial fibrillation and early treatment are of great significance for preventing stroke, preventing heart enlargement and cardiac insufficiency. At home and abroad, more and more attention is paid to atrial fibrillation screening. Several major heart rhythm societies such as AHA, ACC, ESC, and the International Stroke Conference (ISC) often have major research on atrial fibrillation screening appear. In 2017, a consensus document for AF screening was also formed.
There are many screening methods, but each has its own advantages and disadvantages…
In the process of screening for atrial fibrillation, the available methods include blood pressure measurement, pulse palpation, ECG screening, long-term Holter screening, implantable Holter screening, and smartphone screening.
Blood pressure measurement and pulse palpation require certain experience. Blood pressure measurement also needs to be performed in a place with a sphygmomanometer. The convenience is limited, and the sensitivity is not high enough. Electrocardiogram and long-term Holter screening mostly need to be carried out in medical institutions. For patients with a few and irregular episodes of atrial fibrillation, the examination rate is low. The implantable Holter is more expensive and requires an implanted device to only screen for atrial fibrillation. Currently, most patients are unwilling to accept it. At present, smart phones are popular, and almost one person has one. If a smart phone can be used to screen for atrial fibrillation, it will bring great convenience and increase the rate of atrial fibrillation examination. Research on smart phones for atrial fibrillation screening is actively Unfold.
After downloading and installing the heart rate detection software, open the software and there will be a tutorial video inside. After opening it to detect the heart rate, use the flash of the mobile phone camera, use your index finger to hold the camera above the flash, and place your fingers correctly.
The test will be completed in about a minute, and the heart rate index will appear after the test is completed.
The heart rate of atrial fibrillation is generally 350-600 beats every minute, but the atrial rate is fast, and there are generally no obvious symptoms. If this is accompanied by a fast ventricular rate, there will be typical symptoms of palpitations, palpitation, and chest tightness. Fast heart rate means that the ventricular rate is greater than 80 beats every minute at rest, and the ventricular rate is greater than 110 beats every minute after activity. If this value is exceeded at the time of a seizure, more than 80 beats every minute or more than 110 beats every minute, the electrocardiogram must be perfected. If you find that your heart rate is high or low, it is recommended to ask your doctor. Although mobile phone detection may not be as accurate as the hospital’s equipment, it can also serve as a reference for early preventive screening.
Whether the heart rate is normal or not reflects a person’s health status. Most people don’t test their own heart rate from time to time. Now the mobile phone has a heart rate detection software that can detect the heart rate. Here’s how to use it.
