Pacing-induced heart failure as a function of age following external electrical pacing from outbred wild type offspring (yw x Canton S). Experiments were performed at both 25°C and 29°C for a period of seven weeks. Test temperature alone has no effect on failure rate (Χ2= 0.05, p=0.82). Pacing-induced failure rate is age-dependent for both genders at both temperatures (Χ2>40, p<0.0001). More than 90 flies were used for each sample point. From Wessells et al. (2004).
