Example Embodiment

[0020] like figure 1 Shown is a schematic structural block diagram of an atrial fibrillation detection device 100 according to an embodiment of the present invention. The device 100 mainly includes a collection module 102 , a grouping module 104 , a calculation module 106 , and a comparison module 108 . In other embodiments, it may also optionally include: an activity detection module 110 , a timing module 112 , and / or a reminder module 114 .

[0021] The acquisition module 102 may include various forms, as long as the acquisition module 102 can be used to acquire a user's pulse signal sequence, it is applicable, for example, a device for acquiring a pulse using an oscillometric method. But preferably, in one embodiment, the acquisition module 102 includes a photoelectric sensor and an LED, and collects the user's photoplethysmography signal, that is, the PPG signal, based on the principle of photoplethysmography; then, analyzes each pulse in the PPG signal, And extract and r...

Abstract

The invention discloses an atrial fibrillation detector comprising the following elements: an acquisition module used for collecting a pulse signal sequence and recording pulse time intervals; a grouping module used for ranking the recorded pulse time intervals from small to big, and dividing into groups of a preset number; a calculation module used for calculating a pulse time interval deviation value; a comparison module used for comparing repeatedly collected and calculated pulse time interval deviation value of the preset number with a preset threshold value, determining whether the calculated deviation value is bigger than or equal to the preset threshold value, thus determining whether atrial fibrillation exists or not. The atrial fibrillation detector and an intelligent wearable device having same can improve atrial fibrillation discovery rate, so people can self-operate under non-medical conditions, thus carrying out atrial fibrillation detection.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an atrial fibrillation detection device and an intelligent wearable device including the device. Background technique [0002] Atrial fibrillation, referred to as atrial fibrillation, is one of the most common arrhythmias, and the incidence of atrial fibrillation increases with age. In atrial fibrillation, the heartbeat frequency is not only much faster than the normal heartbeat, but also absolutely irregular, and the atrium loses effective contraction function. Atrial fibrillation is prone to complications such as cerebral infarction, thromboembolism, cardiac insufficiency, and sudden cardiac death, among which 20% of stroke events are related to atrial fibrillation. AF increases the risk of arterial thromboembolism and ischemic stroke fivefold. Therefore, if atrial fibrillation is detected and treated in time, the incidence of complications can be greatly reduced. [0003] ...
