Background:Atrial standstill is one of the important clinical consequences on the heart in severe hyperkalemia, but it occurs even at modest potassium ion elevation. The extent to which other factors might potentiate the electrocardiographic changes induced by hyperkalemia remains unclear.Methods and Results:This was a retrospective review of the data on 12,639 hospital admissions over a 15-year period. A total of 778 patients with hyperkalemia were identified, 28 of whom had atrial standstill, and had several parameters measured prior to any treatment of hyperkalemia. Patients with atrial standstill were older (P=0.036), had lower diastolic blood pressure (DBP; P<0.0001) and serum sodium concentration (P<0.0001), higher serum potassium (P<0.0001), and high prevalence of angiotensin converting-enzyme inhibitor (ACEI; P=0.009) or mineral corticoid receptor (MR)-blocker (P=0.006), compared with those without atrial standstill. On multivariate logistic regression, DBP <67 mmHg (P=0.006), serum sodium ion <135 mmol/L (P=0.006) and serum potassium ion >6.1 mmol/L (P=0.018) were identified as independent indicators of atrial standstill, after adjusting for sex, age, chronic maintenance hemodialysis, diuretics use or ACEI/angiotensin receptor blocker and MR blocker.Conclusions:Hyponatremia and decline in DBP are associated with atrial standstill in patients with hyperkalemia.
