Palpitations with shortness of breath occur because the rapid heartbeat leads to increased myocardial oxygen consumption, myocardial ischemia and hypoxia, and the usual respiratory rate can no longer meet the needs of the body, so it always feels short of breath, and some patients often say that there is not enough breath. Therefore, the treatment of palpitations and shortness of breath can be symptomatic, and if available, it is best to inhale oxygen to improve the manifestation of myocardial hypoxia. Also reduce the triggers, such as avoiding emotional excitement, avoiding exertion, and choosing a comfortable position for rest. Also relax, don’t be nervous, and for patients who are emotionally agitated and can’t relax, also apply sedative and tranquilizing drugs, and if necessary, apply anti-arrhythmic drugs to keep the heart rate within the appropriate range. The premise should be examined, for example, the simplest is the electrocardiogram, which can observe whether there is insufficient blood supply to the heart muscle and the rhythm of the heart, so as to guide the use of drugs.
