Acute cardiac tamponade secondary to perforation of the right ventricle during a transient transvenous electrode catheter insertion, occurred in a 79-year-old man. This perforation may have occurred because the apexical tissue of the right ventricle was fragile. Prompt recognition and treatment of this potentially lethal complication of pacemaker electrode catheter insertion are essential.
