  1. good lecture about blood pressure
    around 22.40 it sounded like capillaries resistence can cause a difference
    in right/left bloodpressure. 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).

  2. doesn’t slowing the heart rate (parasympathetic) increase end diastolic
    volume which in turn increase stroke volume therefore actually increasing
    cardiac output?
