[Effect of ethacizine on the heart conduction system and the indicators of central hemodynamics]
Insights
Ethacizine, an antiarrhythmic drug, effectively treated arrhythmias in patients with coronary heart disease. This study found ethacizine improved cardiac function with minimal impact on hemodynamics and myocardial contractility.
Area of Science:
- Cardiology
- Pharmacology
Background:
- Coronary heart disease (CHD) frequently causes cardiac arrhythmias.
- Developing effective antiarrhythmic drugs is crucial for managing CHD complications.
Purpose of the Study:
- To evaluate the efficacy and safety of ethacizine, a novel antiarrhythmic agent.
- To assess the effects of ethacizine on myocardial electrophysiology, hemodynamics, and contractility in CHD patients.
Main Methods:
- Electrophysiological studies were conducted to assess myocardial automatism and conduction.
- Echocardiography was used to evaluate cardiac hemodynamics and contractility.
- Holter monitoring was employed to assess the antiarrhythmic effect and efficacy.
Main Results:
- Ethacizine demonstrated significant effectiveness in treating cardiac arrhythmias.
- The drug was observed to reduce myocardial conduction.
- Hemodynamics and myocardial contractility remained largely unchanged during treatment.
Conclusions:
- Ethacizine is a promising antiarrhythmic drug for patients with coronary heart disease.
- Its ability to control arrhythmias with minimal hemodynamic impact makes it a valuable therapeutic option.
Abstract:
A trial of the antiarrhythmic drug ethacizine made in the Soviet Union which is an analogue of ethmozine was performed in 38 patients suffering from coronary heart disease. Automatism, conduction and excitation of the myocardium, hemodynamics and the antiarrhythmic effect were studied using electrophysiological methods, echo-cardiography and Holter monitoring. Ethacizine was found effective in arrhythmia. It reduces conduction in small changes of hemodynamics and myocardial contractility.
