However in clinical practise it is a very uncommon cause. more common causes in right/left differences are a narrowing of the aorta between the 2 branches of the brachiocefalic artery en the left subclavian. an other option is a narrowing of one of the previousy named arteries themself. the capillary resistence is more important in the genenal bloodpressure: were artheriosclerosis is the major cause and a generalised condition. lokalized capillary resistance changes as in Raynaud, is not only measured by a normal sphygmomanometer. the digital presure is more important, because there is hardely any change in general blood pressure (in this case the general bloodpressure is the controle value where the digit pressure is the variable: a variation of at least 15 mmHg is a positive result). Jazzy Marti January 16, 2015 doesn’t slowing the heart rate (parasympathetic) increase end diastolic volume which in turn increase stroke volume therefore actually increasing cardiac output?
