Antiarrhythmic peptide (cattle atrium)

Antiarrhythmic peptide, a hexapeptide isolated from cattle atrium, demonstrates protective efficacy against experimentally triggered arrhythmias. It is applied in cardiovascular research fields, including studies on myocardial ischemia and heart failure, using in vitro cardiomyocyte models and in vivo rodent experiments. Research indicates its role in modulating gap junction communication, which is crucial for maintaining cardiac rhythm.
