Patients with ventricular tachycardia can be treated with amiodarone, which is a broad-spectrum antiarrhythmic drug with therapeutic effects on ventricular tachycardia and other arrhythmias; patients who cannot determine the type of tachycardia, patients with hemodynamic instability or patients with organic lesions such as myocardial infarction or myocardial ischemia can be treated with amiodarone; amiodarone can cause a decrease in heart rate and blood pressure, so it should be used with caution in patients with cardiac insufficiency or hypotension; 2. Lidocaine: patients with ventricular tachycardia who have stable hemodynamics and no organic lesions can be treated with lidocaine.
