Digitalis can be used to treat congestive heart failure and arrhythmia caused by various heart diseases. It is generally used in combination with other drugs to effectively improve heart failure. It can also be used for the treatment of patients with atrial flutter. Precautions for the use of digitalis: It should not be used with calcium preparations. In addition, it is not recommended for patients with Wolff-Parkinson-White syndrome. The indications for digitalis are as follows:
1. Heart Failure: It has a positive inotropic effect, which can enhance myocardial contractility and improve heart failure.
2. Arrhythmia: Digitalis drugs have electrophysiological effects and can be used for patients with arrhythmia.
3. Others: Digitalis drugs have a negative frequency effect. By enhancing myocardial contractility and acting on the vagus nervous system, they can reduce heart rate reflexively.
Precautions and contraindications for the use of digitalis are as follows:
1. Digitalis poisoning and allergy to digitalis.
2. Hypertrophic obstructive cardiomyopathy, ventricular tachycardia, poor response to pulmonary heart disease, severe myocardial ischemia, active myocarditis, and extracardiac factors such as anemia, hypothyroidism, and vitamin B1 deficiency.
