Sinusarrest. The sinus node stops firing resulting in a pause in heart beats.

Sinus arrest

During sinus arrest the normal pacemaker cells in the sinus node stop firing. Often an ectopic pacemaker (sometimes from within the sinus node) takes over, but the new rate varies slightly from the old one.
