The first thing you need to do when your heart is suffocating is to identify the cause of the condition, of which the most common cause is heart failure. For heart failure, this includes left heart failure, right heart failure and total heart failure. Panic with the heart holding in is often indicative of dyspnea and is commonly associated with left heart failure. Patients with left heart failure present with mild to severe symptoms of exertional dyspnea, nocturnal paroxysmal dyspnea, sedentary breathing, and acute pulmonary edema. Clinically, diuretics can be given as the basic treatment of asthma, if necessary, the application of cardiotonic drugs. It is recommended to give routine blood test to clarify whether there is infection, and give blood gas analysis to clarify whether there is respiratory failure and the type of respiratory failure, and give ventilator-assisted ventilation to improve respiration if necessary. In addition, it is necessary to pay attention to the presence of electrolyte disorders and other conditions, if necessary, to give the appropriate adjustment.
