ABSTRACT

To the Editor:—  In the November 13 issue of The Journal, page 693, there appears a clinical observation on the rapid heart by Dr. L. S. Luton of St. Louis. In this communication Dr. Luton points out that he has been able to reduce the cardiac rate in cases of paroxysmal tachycardias by asking the subject to bend forward to at least a 90 degree angle.I have also been using this procedure of stimulating the vagus by increasing intrathoracic pressure. Due credit for this observation should be given to Dr. Raymond L. Gregory of the Department of Internal Medicine of the University of Texas. School of Medicine at Galveston. He mentioned in his lectures that an attack of paroxysmal tachycardia is frequently stopped completely or noticeably slowed when a patient bends over to tie a shoelace or other such act which involves a comparable change in position.
