cardiovascular system
• with programmed electrical stimulation
• tendency towards non-sustained ventricular tachycardia compared and sustained ventricular tachycardia
• during intrinsic activity, mice exhibit arrhythmic behavior compared with wild-type mice
• during regular pacing and programmed electrical stimulation at varying frequencies in the absence or presence of isoproterenol
• cardiac myocytes exhibit increased mean peak calcium transients and evoked responses with subsidiary events compared with wild-type cells
• before and after isoproterenol, cardiac myocytes exhibit increased numbers of ectopic calcium transient peaks
• isoproterenol treated cardiac myocytes fail to exhibit evoked responses with subsidiary calcium transient events unlike wild-type cells
