Heart failure （HF） is the end-stage performance and the leading cause of death in cardiovascular disease. All the time， we pay more and more attention to the risk stratification and prediction of HF. Cardiac electrical parameters had shown a broad application prospects in cardiovascular system， and its advantages consist of convenience， security， and no invasion. This review summarizes the application value and the research development of cardiac electrical parameters including QRS duration， ventricular late potential， T-wave alternans， heart rate turbulence， deceleration capacity of rate， heart rate deceleration runs， premature ventricular complexes and non-sustained ventricular tachycardia， which may help clinician to take accurate assessment of HF patients and timely perform intensive treatments to reduce adverse outcomes.
