Patients with tachycardia need to pay attention to the following two aspects in their daily lives: First, maintain good living habits. Keep good habits, stable emotions, and avoid intense emotional fluctuations. Also, do not drink strong tea or coffee, as both contain caffeine, which can trigger or exacerbate tachycardia events. Additionally, avoid overeating or drinking excessively, and engage in appropriate exercise when the condition is stable. Second, adhere to standardized medication treatments. If medications are needed to control the heart rate, they should be taken under the guidance of a doctor, following a proper treatment regimen. Do not arbitrarily follow the advice of other patients when choosing medications for treatment.
