Di-4-ANEPPS is a voltage-sensitive dye in membrane potential. Di-4-ANEPPS allows reaching a time resolution better than 1 ms and exhibits changes in fluorescence of up to 10% per 100 mV. Di-4-ANEPPS is a common tool for mapping cardiac electrical activity. Di-4-ANEPPS demonstrate significant direct irreversible effect on spontaneous heart rate and ventricular impulse conduction in rabbit isolated heart model[1].
