Today, Apple officially pushed watchOS 8.3 version for Apple Watch, bringing privacy reports and mindfulness and other functional updates, of which the attention is a feature of three years ago - mobile electrocardiogram atrial fibrillation prompt software (ECG), which is commonly known as the electrocardiogram function.
In fact, as early as the release of Apple Watch Series 4, the function has been supported at the hardware level, but because it has not passed the review of the State Food and Drug Administration (CFDA) at that time, so the function can not be launched in the Chinese mainland for the time being, and now, the user's long-desired function can finally be used.
Equipment Requirements:
Apple Watch Series 4 and later models (except apple Watch SE) requires an Apple Watch upgrade to watchOS 8.3 and an iPhone paired with it needs to be upgraded to iOS 15.2.
Special Reminder:
The official name of the ECG feature provided by Apple Watch is mobile ECG atrial fibrillation prompt software and mobile pulse rate atrial fibrillation prompt software. This feature is not a substitute for medical devices, so if you feel chest pain, chest tightness, chest urgency, or think you have had a heart attack, call emergency services.
Quickly obtain an ECG in 30 seconds
To use this feature for the first time, you need to turn on the "Electrocardiogram (ECG)" function in the health app on your iPhone, and then set your birth date here to use it.
Enter the ECG application on the watch end, put your thumb on the digital crown according to the prompts (without pressing), the whole process will last for 30 seconds, during which try not to move anything, otherwise it will affect the test results.
On the Apple Watch, not only can you see the test results, if there are any discomfort symptoms, you can also fill in here, and the background will merge these data and record them for later viewing.
In the iPhone health APP, you can also view the data results of each measurement, you can also open a piece of data, export a complete PDF file backup, and you can use it as a sample for doctors to reference historical data when you go to the doctor.
After testing many times, it was found that the whole detection process is best not to move, so it is best to use a sitting position or lie down, put your wrist flat on the table or chest, and keep breathing evenly, and let it stand for 30 seconds to get more accurate data.
Are the test results credible?
Before answering this question, let's talk about how the ECG feature of the Apple Watch works.
Human heart beat will produce electrophysiological activities, that is, electrical pulses, when the finger touches the digital crown, the sensor and the crown at the bottom of the watch form a complete circuit, Apple Watch can obtain this information, and then through the algorithm to understand the heart's upper and lower chamber beat rhythm, recorded data, that is, electrocardiogram.
In general, if sinus rhythm is shown, it means that the heart is beating in a regular pattern, indicating that the heart is beating normally during the test period. If atrial fibrillation (AFib) occurs, irregular beating may occur, which is the main manifestation of arrhythmias, which may cause problems such as blood clots and heart failure in the heart, which need to be paid attention to.
It may also indicate a high heart rate (>120 beats/min) and too low (less than 50 beats/min), which requires medical attention as soon as possible.
Although Apple has repeatedly stated that the data results are "for reference only" and repeatedly stressed that if there is discomfort, it will be treated immediately, so is this data still useful?
In fact, as early as three years ago when Apple Watch Series 4 was listed, it was certified by the US FDA (US Food and Drug Administration), on June 25 this year, the State Drug Administration of China also certified the Apple Watch's mobile electrocardiogram (ECG) and atrial fibrillation prompt software, you know, China's requirements for medical devices are more stringent, certification is not easy to pass, get CFDA certification, indicating that its test results have met the relevant national standards, It can be trusted.
In daily life, it can be used as a basis for personal preliminary screening, after all, going to the hospital to register and queue up for examination is time-consuming and laborious, and the general family will not be equipped with professional ELECTROCardi equipment, for the vast majority of ordinary users, even can not understand the ECG results. The Apple Watch simplifies all of this, providing complete data records, analysis reports, and being able to detect abnormalities in the body as early as possible.
Finally, we still want to remind everyone that if you find any discomfort, please seek medical attention immediately, and provide the data detected by the Apple Watch to the doctor for early treatment.
