Arrhythmias can be present in all normal people, and they can be present in 60% of normal people, including infants, adolescents, and the elderly. In a typical arrhythmia, the patient does not have any clinical manifestations, but is found during physical examination, and more sensitive people may have clinical manifestations such as panic, protrusion of the heart, and a feeling of cardiac arrest. If there is no clinical manifestation, in principle, it is clinical observation and does not require any treatment. If there is obvious clinical manifestation, consider giving anti-arrhythmic drugs. It is important to pay attention to rest, avoid straining, ensure good mood and stable sleep, and avoid risk factors that induce arrhythmic symptoms. In clinical practice, oral medications are the mainstay, and if you can do without drugs, try not to use them, pay attention to rest, and maintain good habits, you will not develop this condition.
