What is atrial fibrillation Atrial fibrillation and atrial fibrillation are a type of cardiac arrhythmia. In atrial fibrillation, the frequency of atrial excitation reaches 300 to 600 beats per minute, and the ventricular frequency (heart rate) is often fast and irregular, sometimes up to 100 to 160 beats per minute, which is not only much faster than a normal heartbeat, but also absolutely irregular, and the atria lose their effective contractile function. Common risk factors for atrial fibrillation Advanced age, hypertension, history of heart failure, diabetes mellitus, sleep apnea syndrome, cardiovascular disease, structural heart abnormalities, thyroid disease, transient ischemic attack, alcohol consumption, family history of atrial fibrillation. Common symptoms of atrial fibrillation 1. Patients with atrial fibrillation may experience prodromal ang symptoms due to heart rhythm disturbances, including dizziness or fainting, palpitations, easy fatigue, and shortness of breath. 2. Some patients with atrial fibrillation may be asymptomatic until complications of stroke light appear before a clear diagnosis is made. A simple pulse palpation can diagnose atrial fibrillation Step 1 With the palm of the left hand up, place the index and middle fingers of the right hand together and place the fingers on the lateral edge of the left wrist. Step 2 Slide the fingers of the right hand until you find the location of the pulsating vessel Step 3 Apply finger pressure to clearly palpate the pulsation Step 4 Continue for 1 minute, noting whether the pulsation rhythm is regular or not, a regular pulsation appears to be uniform. A simple pulse palpation can diagnose atrial fibrillation. The International Stroke Association recommends that a pulse check be performed once a month to help identify atrial fibrillation early and to prevent stroke. When checking the pulse, the focus should be on whether the pulse when rhythm is regular, rather than just recording the number of pulses. In other words, it is the regularity of the rhythm of the heartbeat in a minute that needs to be looked at, not the number of heartbeats. If you find that your pulse is irregular, please seek medical attention. Your clinician will recommend that you undergo relevant tests to clarify whether it is atrial fibrillation. If atrial fibrillation is diagnosed, your doctor will develop an atrial fibrillation treatment strategy.
