Use your data to support the specific physiolgical principles demonstrated in your part of the
     experiment.
 

 
Section A:

     Record:   One record of normal at paper speeds of 1 cm/sec and 5 cm/sec., followed by
                     vagal stimulation at 5 cm/sec.

     Discussion
 

 
Section B:

     Records:    1.    Ventricular systole and diastole.
                       2.    Starling's Law

     Discussion
 

Section C:

     Records:     1.    Absolute and relative refractory periods.
                              Cut out four sequential stimulated curves, showing the point of stimulation
                              along the time and event line. Rearrange these curves in order of stimulation
                               to make one composite record. From this composite prepare and attach an
                               unstimulated myogram showing the approximate absolute and relative
                               refractory periods based on the points of stimulation of the four ventricular myograms.

                        2.    Attempt of ventricular tetanization

     Discussion
 

Section D:

     Record:    The effect of temperature

     Graphs:    1.    Prepare and fully label a graph of temperature versus rate.

                      2.   Prepare and fully label a graph of temperature versus amplitude expressed in
                            centimeters of pen deflection.
