Since my last communication on this subject,1 I have had an interesting experience in another case, and my success in stopping the attack leads me to record it and to state the rationale of the method.

Patient.  —Miss C. has had many attacks of paroxysmal tachycardia during the last five years, during which time she has been under my observation. The case has been previously described in detail.2 The method successfully tried in my other case1 had been described to her, but she had been unable to influence any one of her infrequent attacks and I had not seen her during an attack in the interval.

Treatment.  —January 18, at 4 p. m., the patient came to my office complaining of a rapid heart. It had begun at 8 o'clock in the morning. I counted the apical systoles with a stethoscope and found the rate 220 per minute.
