Biological pacemaker in the heart of the initial stage, many of the problems facing the clinical application, but as the molecular biology and gene. Engineering technology, biological heart pacemaker will benefit mankind. , Key words: biological pacemaker; cell therapy; gene therapy Abstract: Thecardiacbiologicalpacemakeristhefocusofcardiacpacemakinginrecentyears.

Keywords: biologicalpacemaker; celltherapy; genetherapy electronic pacemakers used clinically more than 70 years of history. 70 years, the artificial heart pacemaker technology is gradually improving, electrical energy from the pacemaker of a mercury-zinc battery development for lithium battery, electrode wire has also been great progress, in order to better apply to the physiological state, since developed from a single chamber pacemaker to a dual-chamber, three chamber,[link widoczny dla zalogowanych], four or even cavities. Clinical indications are continuously expanding, from the sick sinus syndrome, cardiac conduction system diseases,[link widoczny dla zalogowanych], such as extended to the treatment of intractable heart failure, ventricular fibrillation and other non-conduction system disease, save a large number of patients. Electronic pacemaker, but also exposed some shortcomings: (1) of battery life, need 8 to 10 years pacemaker reoperation replaced; (2) can be infection, bleeding,[link widoczny dla zalogowanych], electrode dislocation, complications such as pacemaker syndrome ; (3) are expensive and require long-term follow-up to detect the pacemaker working status; (4) has failed to properly address the physiological electrical activity of the heart of the order of excitement, pacing to achieve the ideal state; (5) age too smaller ones should not be vulnerable to electromagnetic fields in the surrounding environment,[link widoczny dla zalogowanych], etc.; (6) lack of
