The presence of panic, shortness of breath and fast heartbeat and dizziness are emergencies and require emergency treatment. 1. Blood pressure, blood sugar and electrolyte abnormalities: In case of panic, shortness of breath and fast heartbeat and dizziness, it is recommended to immediately rest in bed and quickly call the hospital 120 to go to a regular hospital for treatment. After arriving at the hospital, quickly measure blood pressure, blood sugar and electrolytes to see if there is particularly high blood pressure or hypoglycemia, electrolyte disorders, etc. If the above-mentioned diseases occur, the symptoms can be quickly relieved after giving the appropriate medication. 2, cardiovascular disease: In the hospital, we also need to perform electrocardiogram, cardiac ultrasound and 24-hour ambulatory electrocardiogram to see if there is paroxysmal atrial fibrillation and paroxysmal supraventricular tachycardia. Because these cardiac diseases can cause insufficient blood supply to the brain, which in turn can cause dizziness symptoms. If necessary, perform coronary angiography to look for coronary stenosis and to further rule out precursors of myocardial infarction. If necessary, cranial CT or MRI or transcranial Doppler examination will be performed to check for cerebrovascular lesions, and corresponding treatment will be given according to the examination results. In conclusion, the most common causes of shortness of breath and rapid heartbeat include blood pressure, blood sugar and electrolyte abnormalities as well as cardiovascular and cerebrovascular diseases, and the causes need to be identified as quickly as possible for proper treatment.
