Hello, 1. Considering your symptoms, the first thing to consider is tachycardia, especially atrial fibrillation. It's best to do an electrocardiogram in the morning to determine the type of arrhythmia, and then pay attention to your supraventricular arrhythmia, because deep breathing can stop it.
Attention should be paid to the current treatment of tachyarrhythmia, which needs to be combined with the usual heart rate and whether there are basic cardiovascular diseases, especially the structure and function of the heart.
It is suggested to actively go to the cardiology department for treatment, make clear the specific situation, carry out reasonable targeted treatment, consult in time if you have any questions, and wish you good health.
