Increased heart rate after exercise following recovery from yang (positive/active phase, e.g., post-COVID-19 infection)

“Post-Yang” generally refers to the period after infection with the novel coronavirus. An increased heart rate during exercise following a COVID-19 infection may be caused by factors such as incomplete physical recovery, excessive exercise intensity, psychological factors, neurological dysfunction, or myocarditis. Appropriate measures can be taken depending on the specific cause. It is recommended to seek timely medical evaluation and treatment under the guidance of a physician.

1. Incomplete physical recovery: After infection, organ functions—including cardiopulmonary function—are still recovering. During exercise, the body's oxygen demand increases, placing additional strain on the heart and lungs, which respond by increasing heart rate to meet oxygen needs. Reduce exercise volume and intensity appropriately, gradually increasing duration and frequency to allow sufficient recovery time.

2. Excessive exercise intensity: The body remains relatively weak post-infection. If exercise intensity exceeds physical tolerance, the heart must beat faster to deliver more oxygen and nutrients to muscles, leading to tachycardia. Adjust the exercise plan by choosing low-intensity, slow-paced activities such as walking, yoga, or tai chi, and avoid vigorous exercise.

3. Psychological factors: Some individuals may experience worry or anxiety about their health after infection. This psychological stress can intensify during exercise, stimulating the sympathetic nervous system and causing an elevated heart rate. Focus on maintaining a positive mindset and use techniques such as deep breathing, meditation, or listening to music to relieve tension before exercising.

4. Neurological dysfunction: Following infection, the nervous system may become dysregulated, disrupting the balance between the sympathetic and parasympathetic nervous systems. This imbalance becomes more pronounced during exercise, resulting in increased heart rate. Under medical supervision, medications such as Oryzanol tablets, Vitamin B Complex tablets, or Wenxin Granules may be used for treatment.

5. Myocarditis: The infection may affect the myocardium, leading to myocarditis. When heart muscle is damaged, normal cardiac function is impaired. During exercise, the increased cardiac load can result in a rapid heartbeat. Under a doctor’s guidance, patients may take Coenzyme Q10 capsules, Vitamin C tablets, or Trimetazidine tablets to alleviate symptoms.

In general, individuals should engage in appropriate physical activity based on their own condition, avoiding intense exercise. It is important to control both exercise volume and duration. Light activities such as walking or jogging—adjusted according to individual capacity—can help enhance immunity and support recovery.
