Chest Pain
In some severe cases of atrial fibrillation, chest pain might occur. It could be sporadic and improve after a couple of minutes, but it would also persist and cause painful sensations. No matter the severity and frequency, you need to seek immediate medical emergency as this can be a life-threatening sign. Sometimes, even a slight pain in the chest would indicate an upcoming heart attack. Thus, it is important to visit your healthcare provider as soon as you notice the symptom. Otherwise, it would even lead to death. [7]
