循环答案（Loop answer） [and] the problem First, the noun explanation 1. heart failure refers to various heart diseases caused by abnormal structure and function of heart damage, ventricular filling and / or ejection function, resulting in reduced cardiac output, increased venous pressure, with clinical syndrome of pulmonary circulation and / or systemic circulation and tissue hypoperfusion as the main feature. 2. ventricular remodeling is defined as the pathological changes in the geometric shape of the heart, the myocardial cells and their mesenchymal components, and the phenotype of the cardiomyocytes that undergo a series of changes in the pathogenic factors. 3.: sinus arrest (or sinus arrest) refers to the sinoatrial node in a long time can not generate excitement, make the heart temporarily arrest, or a lower level pacemaker (such as atrioventricular junctional or ventricular arrhythmia) issued excited control. 4. multiple ventricular premature contractions: ventricular premature contractions in the same lead, if there is a difference in shape, and the distance between the previous heartbeat (paired interval) is not fixed, referred to as multi-source ventricular premature contraction. 5. ventricular parallel rhythm: if ventricular ectopic pacemaker points out the excitement independently and can prevent sinus invasion, then ventricular parallel rhythm is formed. The ECG manifestations were as follows: (1) the pairing interval was not constant; the two long ectopic beats were the shortest multiples of the two ectopic beats intervals; and they could produce ventricular fusion waves. The 6. ventricular fusion wave: such as the occurrence of late ventricular extrasystoles, ventricular and hand to accept the sinoatrial node under excited hand by the premature ventricular contraction excited QRS wave pattern between sinus extrasystole between QRS wave shape, the formation of ventricular fusion wave. The presence of sinus P wave. 7. cardiac arrest: refers to the heart pump
