摘要: Disopyramide is effective and safe in patients with obstructive hypertrophic cardiomyopathy. However, its cellular molecular mechanisms of action are unknown. We tested disopyramide cardiomyocytes from the septum surgical myectomy patients: inhibits multiple ion channels, leading to lower Ca transients force, shortens potentials, thus reducing arrhythmias. The electrophysiological profile explains efficient reduction outflow gradients but also limited prolongation QT interval absence arrhythmic side effects observed 39 disopyramide-treated patients. In conclusion, our results support idea that for outpatient use
