The symptoms of cardiac disease of the heart muscle are mainly palpitations or panic. For this group of patients, it is common in patients with first, sinus tachycardia, atrial tachycardia, as well as atrial fibrillation and atrial flutter. For these patients, they can show symptoms of panic, stuffiness, shortness of breath, and dizziness. They should be actively given drugs such as betalactam to control the ventricular rate and slow down the heart rate, so as to improve the clinical symptoms of the patients. Secondly, for the deadly tachycardia, cutting-edge obvious torsional ventricular tachycardia, or even ventricular fibrillation, ventricular flutter and other serious malignant arrhythmias, patients will also have panic, chest tightness, dizziness, and in serious cases, syncope and sudden death, and should be actively given drugs to convert the sinus rhythm, so as to improve the symptoms of the heart muscle. If necessary, emergency electric defibrillation is given to restore power and thus stabilize hemodynamics and reduce the incidence of sudden cardiac death.
