Transient sinus arrest due to sinus node artery thrombus after revascularisation of the left circumflex artery

BMJ Case Rep. 2019 Feb 22;12(2):e227878. doi: 10.1136/bcr-2018-227878.

Abstract

We present a case of sinus arrest and junctional escape rhythm from sinus node artery (SNA) thrombus in a 55-year-old man after revascularisation of right coronary and proximal circumflex arteries for infero-posterior wall ST-segement elevation myocardial infarction (STEMI). Sinus arrest from occlusion of the SNA is uncommon. The ensuing bradycardia may have haemodynamic consequences requiring temporary pacing but is almost always self-limited.

Keywords: arrhythmias; interventional cardiology; ischaemic heart disease.
