Given concerns regarding electrode fixation and risk of dislodgement, transvenous implantation of a tined endocardial electrode into the right atrium is considered difficult in patients who require permanent atrial pacing following cardiac surgery. Implantation of a tined endocardial electrode into the right atrium was performed intraoperatively for 3 patients who required implantation of a permanent atrial electrode during the cardiac operation. This technique yielded excellent results during the mean follow‐up period of 65 months, with low stimulation thresholds (mean 2.85 P), sufficiently high sensing thresholds (mean 2.23 μJ) and stable lead impedances (mean 491.7 ohm). This technique offers a useful and secure method for patients with preoperative bradycardial arrhythmias who require implantation of a permanent atrial electrode during open‐heart surgery.
