   Twenty Iraqi ducks hearts ( 10 male and 10 female ) have been  used for   demonstration  and illustration of heart's valves  and chambers  as well as  anatomical   and morphological site of view to explain what modifications had been take place for ducks heart  to perform  his normal life at the  circumstances  of  high  blood  pressure  and  pulse  rate. The heart  which has distinctly pointed  apex  was  built   in simple  manner located  in a transparent  taught  heart  pericardial  sac. It   was pyramidal in shape  externally  and  has a longitudinal  salcus  passing  to the  right  side, the  anterior of  the   heart  is  divided  into two  unequal  anterior  chamber  similar  to  those of mammalian  hear  .The heart valves are modified  in  order to  minimize  the  fraction  that occur as a result of  high  blood  pressure  and  pulse  rate  of  the  duck  heart , also  the  muscular  trabeculae   replace  the  chordate  tendineae  , which  were  present in the  mammalian    heart  in order to  minimize  the  fraction  resulting  from high  pulse  rate..

The author, making parallel experiments on young people and old people (lifting with legs of a certain weight), came to the conclusion that the senile heart is not able to maintain that high blood pressure for a long time, which happens during intense physical work, since such a heart is not in a state to accelerate the pulse rate.

The blood pressure and pulse rate of 90 normal rabbits have been studied for various periods of time, from 1 day (accidental death interrupting the observation) to 15 months. The main data are presented in a table containing the blood pressure and pulse rate on the 1st day of observation, the maximum and minimum of both during the entire period of observation of each animal, together with the sex and weight of the animal. Separate tables are given showing the distribution of blood pressure, pulse rate and the "maximum" blood pressure by animals. Detailed data on two animals observed for the longest time are given in tabular form. The anatomical changes that occur in some carotids enclosed in a loop are described and discussed. Considerations on "excitement" and pathological conditions which arise spontaneously in rabbits are given. A criterion for a pathologically high blood pressure in rabbits is proposed. The blood pressure of the normal rabbit ranges between 70 and 170 mm. Hg. The pulse rate, taken simultaneously with the blood pressure, fluctuates between 112 and 300 per minute.

High resting pulse rate (RPR) is associated with adverse cardiovascular events, and could be used as a marker of cardiovascular health. We determined the correlation between RPR and blood pressure (BP); and its accuracy in defining high blood pressure among adolescents attending secondary schools in Mbarara municipality, south-western Uganda. We conducted a cross-sectional study among secondary school adolescents aged 12-19 years in Mbarara municipality, Uganda. We captured demographic characteristics using a structured questionnaire; and measured anthropometric indices and BP. We performed a linear regression analysis to determine the relationship between RPR and blood pressure and plotted receiver operating characteristics curves (ROC) to assess the accuracy of RPR in defining high BP. We enrolled 616 adolescents with a mean age of 15.6(2.0) years and 65.6% (404/616) were female. The RPR was significantly correlated with diastolic blood pressure (DBP) in both boys (Beta = 0.22 [95%CI: 0.10; 0.36]), p<0.001 and girls (Beta = 0.51 [95%CI: 0.43; 0.60]), p<0.001. RPR was significantly correlated with systolic blood pressure (SBP) only in the girls (Beta = 0.23 [95%CI: 0.15; 0.30]), p<0.001. The optimal threshold for RPR in defining prehypertension was RPR≥76bpm with an area under the curve (AUC) of 0.653[95%CI: 0.583-0.722], the sensitivity of 0.737 and specificity of 0.577. In defining hypertension, the optimal threshold was RPR ≥ 79bpm at a sensitivity of 0.737 and specificity of 0.719, with an AUC of 0.728[95%CI: 0.624-0.831]. Resting pulse rate was positively correlated with BP and was more accurate in defining hypertension compared to prehypertension in the study.

Objetivo: levantar na literatura atual, estudos relevantes que identifiquem as possíveis respostas hemodinâmicas encontradas em indivíduos hipertensos praticantes do Método Pilates. Materiais e Métodos: Pesquisa de revisão sistemática conduzida conforme as recomendações PRISMA em cinco bases de dados eletrônicas (PEDro, PubMed, SciELO, LILACS e Cochrane), disponibilizado desde o início das bases até Março de 2019, com descritores do dicionário MESH conforme segue: [(“Adult” OR “Young adult” OR “Middle Aged” OR “Aged” OR “Elderly”) AND (“exercise movement techniques” OR “Pilates-Based Exercises” OR “Pilates Training”) AND (“Hemodynamics” OR “Heart Rate” OR “Cardiac Chronotropy” OR “Heart Rate Control” OR “hypertension” OR “Blood Pressure” OR “High Blood Pressure” OR “Systolic Pressure” OR “Diastolic Pressure” OR “High Blood Pressure” OR “Pulse Rate Determination”)], posteriormente ajustado para as demais bases. Busca complementar manual nas referências dos artigos incluídos na pesquisa e no Google Scholar. Foram incluídos estudos de intervenção, com indivíduos de idade maior ou igual a 18 anos; diagnóstico de hipertensão arterial sistêmica (HAS); que tenham sido submetidos a exercícios de pilates solo e/ou pilates aparelhos como método de intervenção e incluído a descrição de análise das variáveis hemodinâmicas de pressão arterial (PA), frequência cardíaca (FC) e duplo produto (DP). Resultados: Após processo de seleção foi selecionado apenas um único estudo que tenha contemplado todos os critérios de elegibilidade, totalizando 44 indivíduos do sexo feminino, com média de idade de 50,5 anos (±6,3 anos), hipertensas com utilização de medicação, onde 22 foram submetidas ao pilates solo e 22 permaneceram no grupo controle. O estudo apresentou resultados positivos na frequência cardíaca (FC), pressão arterial (PA) e no duplo-produto (DP) em comparação ao grupo controle. Conclusão: O Mat pilates pode ser um método aplicável e hemodinamicamente em pacientes com HAS, entretanto, novos estudos devem ser realizados para a confirmação dos achados.
