We report three cases of an unusual form of "reel syndrome" characterized by isolated, reeling dislodgement of a single lead in patients with dual-chamber or biventricular devices. One of these patients presented with worsening heart failure due to loss of left ventricular pacing and the others were detected incidentally during scheduled device checks. We suspect that a ratchet mechanism was probably responsible for this and that this type of dislodgement is not a twiddler variant. We propose a simple solution for prevention.
