Will taking Bilastine along with Escitalopram cause ventricular fibrillation?

Hello,

Welcome to icliniq.com.

I passed carefully through your medical history and would like to explain that your previous medications could have played a role in triggering the cardiac arrhythmia episode. Escitalopram has been mentioned more frequently as a cause of arrhythmic events as it may cause QTc interval prolongation on ECG (electrocardiography). Bilastine in fact has not been confirmed as a direct proarrhythmic agent. Anyways, a combination could have produced an exaggerated effect. From the other side, separated cardiomyopathy, serving as an important arrhythmogenic substrate cannot be excluded. A cardiac MRI (magnetic resonance imaging) study would have been the most appropriate test to carefully characterize the cardiac tissues. But, actually after ICD (implantable cardioverter defibrillator) implantation, some artifacts would be present during that study and the conclusions may be compromised. I recommend following QTc interval evaluation with periodic ECG, and checking also blood electrolytes level. In case of a certain cardiomyopathy, genetic testing could be helpful. I hope this helps.
