Poor sleep can cause panic and palpitations mainly because poor sleep can cause increased sympathetic excitability in patients, resulting in increased heart rate and increased myocardial contraction, thus causing palpitations to occur. As poor sleep can induce the occurrence of arrhythmias such as premature beats, it can also lead to panic and palpitations. Therefore, for patients with poor sleep, sleep improvement drugs can be given to improve sleep and thus relieve the symptoms of panic and palpitations. In case of panic and palpitations, it is also necessary to actively improve relevant examinations to determine whether there are associated diseases, such as hyperthyroidism, arrhythmia, and other heart diseases, such as coronary heart disease, myocarditis, cardiomyopathy, etc. If related diseases are present, treatment should be actively given.
