Comparative Analysis of Mammalian Heart Rates

HR, maximal life expectancy, body size and the resulting number of heartbeats per lifetime were obtained from data available in the literature for different mammals including 10 species of primates, 12 species of rodents and 9 species of domestic mammals from different orders. In particular we took in consideration the species GML, common marmoset (Callithrix jacchus)^{80 (link),81 (link)}, squirrel monkey (Saimiri sciureus)^{82 (link),83}, capuchin Monkeys (Cebus apella)^{66 (link)}, rhesus macaque (Macaca mulatta)^{84 (link),85 (link)}, chimpanzee (Pan troglodytes schweinfurthii)^{86 (link)}, Babouin hamadryas (Papio hamadryas)^{87 (link)}, orangutan (Pongo pygmaeus pygmaeus)^{88 (link)} and gorilla (Gorilla gorilla gorilla)^{89 (link)}, in comparison to humans⁵⁵ for the primate order; mouse^{45 (link)}, hamster^{64 (link),90 (link)}, rat^{47 (link)}, Mongolian gerbil (Meriones unguiculatus)^{91 (link),92} guinea pig⁹³, red North American red squirrel (Tamiasciurus hudsonicus)^{2 (link)}, muskrat (Ondatra zibethicus)^{94 (link)}, marmot (Marmota monax)^{95 (link)}, capybara (Hydrochoerus hydrochaeris)^{96 (link),97 (link)}, agouti (Dasyprocta primnolopha)⁹⁸, North American Porcupine (Erethizon dorsatum)^{95 (link)}, north american beaver (Castor canadensis)^{94 (link)} for rodents and rabbit^{99 (link)}, dog^{99 (link),100 (link)}, sheep^{101 (link)}, cat^{102 (link)}, pig^{103 (link)}, goat^{104 (link),105 (link)}, donkey^{106 (link)}, horse^{107 (link)} and camel^{108 (link)} for the domestic mammals. HR were reported from results obtained in unanesthetized and mainly freely moving animals under resting conditions. Significance was evaluated through paired or unpaired Student’s T test, one-way- and two-way ANOVA and comparison between regression law as specified in figure legends. When testing statistical differences, results were considered significant with p < 0.05. Data analysis was performed with GraphPad Prism 9.0 and IBM SPSS Statistics 28.0.0.0.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
