Primary Sinus Node Defect Present in Subset of Postural Tachycardia Cases

NEW YORK (Reuters Health) Mar 27 – Some patients with postural tachycardia syndrome (POTS) exhibit primary sinus node dysfunction, researchers have determined. They say the finding has important potential therapeutic implications, in that radiofrequency ablation of the sinus node might be appropriate for these patients.
Dr. Phillip A. Low, from the Mayo Clinic in Rochester, Minnesota and colleagues suspected that a primary sinus node abnormality might be involved in some cases of POTS, because POTS symptoms overlap with those of inappropriate sinus tachycardia. They investigated whether analysis of the P-wave axis on electrocardiograms, to determine the origin of cardiac pacing within the sinus node area, could distinguish primary from secondary sinus node dysfunction.
