Integrative review of electrocardiographic characteristics in patients with reduced, mildly reduced, and preserved heart failure

Acute heart failure (AHF) is a rapid decompensation of cardiac function. Most heart failure patients with heart failure symptoms seek treatment in the emergency department and are hospitalized for treatment.1,2 Guideline-directed medical therapy for heart failure is based on types of heart failure categorized based on left ventricular ejection fraction (LVEF). Recent guidelines recommended treatment based on types of heart failure with different cut-offs of LVEF: heart failure with reduced EF (HFrEF, ≤40%), mildly reduced EF (HFmrEF, 41-49%), and preserved EF (HFpEF,>50%).
