Common approaches to cardiac discomfort caused by increased sympathetic arousal include stimulation of the pallidum, use of beta-blockers, use of benzodiazepines, psychological counseling, and anti-anxiety medications. 1. Stimulation of the palate: Stimulation of the palate with a tongue depressor or chopsticks or spoons induces nausea and vomiting, which excites the vagus nerve. For the heart, sympathetic excitation will promote the contraction of the heart muscle and the conduction function of the sinus node of the heart, which will speed up the heart rate and increase the blood pressure, and the vagus nerve can inhibit the heartbeat and inhibit the conduction of the heart. 2. Use of β-blockers: including propranolol, Aroclor, etc., can reduce the sensitivity of β-receptors and thus inhibit the symptoms caused by sympathetic over-excitation. 3. The use of benzodiazepines: such as alprazolam and clonazepam can be used for acute sympathetic arousal. 4. Psychological counseling and anti-anxiety drugs: For functional sympathetic hyperactivity, psychological counseling and anti-anxiety drugs such as meprobamate, calypodol and other aminocarbamate drugs are given. If the symptoms are obvious, it is recommended to go to the hospital in time, clarify the cause of the disease, symptomatic treatment, and use drugs under the guidance of the doctor.
