Sino-atrial node block is a condition characterized by a slowed (or interrupted) electrical impulse transmis- sion from the sino-atrial node to the atrium.¹ The sino-atrial dysfunction potentially leads to sinusal arrest, bradycardia up to asystole, syncope and cardiac arrest. In such situations, a temporary or permanent pacemaker implantation is necessary. Different causes may be responsible for sinus atrial block, more frequently vagal hypertone, ions alterations, myocarditis and iatrogenic causes.^2-9 We report the case of a sixty-year-old man with Guillain-Barré syndrome who required pacemaker implantation for II to III degree sino-atrial block and symptomatic pauses lasting 2.8 s.
