DISTURBANCES OF THE HEART IN GENERAL


Of prime importance in the treatment of diseases of the heart is a
determination of the exact, or at least approximately exact,
condition of its structures and a determination of its ability to
work.

This is not the place to describe its anatomy or its nervous
mechanism or the newer instruments of precision in estimating the
heart function, but they may be briefly itemized. It has now been
known for some time that the primary stimulus of cardiac contraction
generally occurs at the upper part of the right auricle, near its
junction with the superior vena cava, and that this region may be
the "timer" of the heart.
