In a recent collaboration with Merck, Biopta conducted human functional tissue experiments to investigate the mechanisms underlying two anti-arrhythmic drugs. Hemodynamic effects are often noted as adverse events with the use of antiarrhythmic drugs, including those used for the treatment of atrial fibrillation.
