We present two cases with unexpected long sinus arrest resulting in syncope. There were no signs or symptoms of either sick sinus syndrome or increased vagal tone before the occurrence of pauses in these patients. The fact that these patients remained asymptomatic for quite long shows striking resemblance to paroxysmal sub-AV nodal block.

We would therefore prefer to classify these cases as paroxysmal sinus arrest as a possible manifestation of the sick sinus syndrome. (C) 2019 Elsevier Inc. All rights reserved.
