To the Editor.—
The report in the Archives by Rush et al titled "Paroxysmal Atrial Tachycardia and Frontal Lobe Tumor" (34:578-580, 1977) suggests that a 49-year-old male patient had symptoms secondary to paroxysmal atrial tachycardia (PAT) and that the PAT was secondary to seizure activity related to a frontal lobe glioma. Unfortunately, this report gives no documentation that the patient had PAT and, in addition, there is no evidence that his symptoms were in any way related to a change in cardiac function. Certainly, these symptoms cannot be explained by a pulse rate of 110 beats per minute.It is possible that the patient's spells could have been partial seizures with an associated mild sinus tachycardia. Figure 1 showing four channels of EEG monitored during one of the patient's spells is small, making interpretation difficult. However, I see no clear electrical seizure activity, although this possibility cannot be ruled out
