This report describes two cases of double sensing of the P and QRS signals by an implanted atrial bipolar automatic burst tachycardia‐terminating puise generator (Inlermedics CyherTach 60) used for the treatment of supraventricular tachycardia. Double sensing occurred during normai sinus rhythm at a rate slower than the tachycardia detection criterion and caused inappropriate delivery of burst stimulation. These observations underscore the importance of the far‐field QRS signal in the detection of supraventricular tachycardia by automatic puise generators sensing the atrial eiectrogram.
