Abstract P018: Poincare Plot Asymmetry is Associated With Sudden Cardiac Death in the Community: The Atherosclerosis Risk in Community Study

Introduction: Poincare plot asymmetry has been associated with sustained ventricular tachyarrhythmias, implicating involvement of the autonomic nervous system. An association between sudden cardiac death (SCD) and Poincare plot asymmetry has not previously been studied in a general population cohort. Porta index measures time asymmetry in heart rate variability (HRV), corresponding to disproportionate relative tachycardic predominance....
