1, pay attention to rest in the treatment of viral myocarditis why is significant?
According to experimental studies, mice forced to swim after inoculation with the coxsackie B3 virus, the virus titer in the serum and heart is higher than that of mice infected with the virus and not exercising. A case was found in which a person with repeated manifestations of first-degree AV block was treated, rested, and basically stabilized without further AV block after 2 years, but his physical strength was worse than before and he did not participate in strenuous physical activity again. After another year, he developed chest tightness and cold sweats during an occasional invitation to a basketball game, and the P-R interval was prolonged from 0.18 seconds to 0.20 seconds in the ECG the next day, indicating that in some patients with viral myocarditis, overexertion can worsen the disease. Rest is of great importance in the treatment of patients with viral myocarditis.
Adequate rest and prevention of overexertion is the key to treating viral myocarditis, especially since there are no specific drugs for myocarditis. Once the disease is diagnosed, the patient should rest in bed until the body temperature drops to normal for 3-4 weeks, wait for the ECG and X-ray changes to return to normal, and then gradually get up and move. The day of rest is to reduce the burden on the heart to prevent heart enlargement and further deterioration of the disease. Overexertion increases the dirty load on the one hand, and induces heart failure and arrhythmia on the other, even leading to sudden death.
By resting, the body needs less blood flow, and the workload of the heart is bound to decrease. Therefore, proper rest is also of extreme importance in the treatment of patients with myocarditis complicated by heart failure. Rest lowers blood pressure, reduces or eliminates dyspnea, slows the heart rate, and thus reduces the oxygen consumption of the heart. Conversely, some patients with mild heart failure can suffer from acute pulmonary edema or acute left heart failure due to inattention to rest.
Once viral myocarditis is recovered or heart failure is controlled, it is not advisable to give unrestricted rest, and excessive rest is not allowed for disease recovery. Long-term bed rest can cause adverse effects such as venous thrombosis, pulmonary embolism, indigestion, loss of appetite, constipation, muscle atrophy, osteoporosis, emotional depression, weakened resistance, low heart reserve and bed sores. Here we advocate active rest, not absolute bed rest, that is, from the overall point of view, take the principle of combining movement and static, and according to the patient’s physical recovery, gradually increase the amount of activity, in order not to feel tired. The amount of activity should not be increased at once too large, too fast, but gradually, according to the ability to do. The actual fact is that you can find a lot of people who have been in the marketplace for a long time, and they’ve been in the market for a long time.
The actual fact is that you will be able to get a lot more than just a few of the most popular and popular items.
The benefits include: promoting the formation and development of myocardial collateral circulation, improving the supply and demand of myocardial oxygen; slowing down the heart rate, strengthening the heart beat, increasing the ejection capacity of the heart, improving myocardial metabolism, and increasing the heart’s reserve capacity; reducing weight, avoiding obesity and increasing the burden on the heart; reducing the excessive adrenergic activity of the heart, and regulating the state of neuropsychiatric activity, eliminating mental tension and fatigue. Viral myocarditis patients should not take strenuous exercise physical exercise way, generally take a walk, jogging, boxing and gymnastics, qigong, cycling, etc..
(1) Walking: walking is a small amount of exercise, especially for patients who have just recovered, is the most convenient and safest way to exercise. Walking can eliminate fatigue, reduce anxiety, adjust appetite, increase sleep, and improve cardiopulmonary function. When walking, you should hold your head high and swing your arms so that all parts of your body are stretched. The speed of the step can be determined according to the health of good, to not feel fatigue as the degree. At first, you can walk at the usual speed as a starting point, and then gradually increase the speed, increase the pace, extend the time and distance. The time spent walking is more important than the speed, at least 2 times a day, each time lies more than 20-30 minutes, must be long-term persistence, in order to effect.
(2) jogging: simple and easy, the effect is better, there is a “fitness run” called, for the more prevalent Hu sports around the world. The actual jogging is still a more strenuous exercise, myocarditis sufferers should be cautious. The lighter, usually more active, can gradually try jogging on the basis of fast walking; weak, usually less active patients do not easily run, can gradually transition from walking to jogging.
(3) boxing and exercise: taijiquan or taiji sword posture relaxed, soft movements, stable rhythm, is also more suitable for myocarditis patients exercise. If you can combine it with walking, it will be more effective. The size of the exercise should also be determined by the condition and physical strength. The poor physical strength can play simplified taijiquan, repeat the exercise. Good physical strength can practice a full set of taijiquan.
(4) qigong: practice qigong to improve physical fitness, the unique features of the rehabilitation of chronic diseases, especially for patients with myocarditis sequelae, according to the condition and interest to choose to practice gong, generally to loose static gong is appropriate.
(5) cycling: If you are used to cycling and have adapted to jogging, you can combine cycling exercise, but the distance and speed should be strictly limited, if there is discomfort, should stop exercise.
