For patients with arrhythmia, it is important to ensure the quality of sleep. Poor rest can aggravate the condition and even lead to dangerous situations such as acute heart attack and acute heart failure. Prone lying is the most inappropriate sleeping position to adopt, because prone lying will compress the heart and lungs, affecting the whistle. Arrhythmia patients, as well as patients, should take the right side of the sleeping position, keep the body natural flexion, because this position is conducive to the return of blood to reduce the burden on the heart. If there is chest tightness and difficulty in whistling, semi-recumbent position or 30-degree angle slope lying position can be taken, so as to reduce the occurrence of arrhythmia. Emotional excitement and mental tension can easily induce arrhythmia. Therefore, before going to bed should not watch exciting, exciting games or programs, and should not drink tea and coffee and other stimulating beverages. As the vagus nerve is excited during sleep, it will slow down the heart rate. For patients with severe sinus bradycardia, sinus arrest, and sinus block, appropriate medications can be taken as prescribed by the doctor to control the condition. Before going to bed, put the emergency medication closer to the bed so that you can reach out and get it to prevent the problem before it occurs. Arrhythmia is one of the common ones in the cardiovascular system, which manifests itself as, bradycardia or arrhythmia caused by an abnormal heart rhythm or conduction disorder. Patients may experience uncomfortable symptoms such as chest tightness, dizziness, and a feeling of cardiac arrest. Arrhythmias often occur in the context of various heart conditions. Ordinary people may also develop arrhythmia. Stress, heavy smoking, drinking alcohol, drinking strong tea or coffee, excessive fatigue, severe insomnia, etc., are all its triggering factors. Therefore, once an arrhythmia occurs, there is no need to be overly nervous, and you should go to the hospital in a timely manner to determine the nature of the arrhythmia and whether there is any underlying disease.
