The identification of endogenous pacemakers and the exploration of their controllability lead to a remarkable progress in human medicine. On cellular basis proliferation and orientation are regulated, and contraction and organ interactions were modulated by pacemaking cells. Dysfunctions lead to acute and chronic organ damage and can be life-threatening. In this respect, overactive as well as underactive pacemaking can bring a person in a very dangerous situation. In the last decades, “artificial” pacemakers made outstanding steps forward, in particular in cardiovascular science. The devices are now able to do much more than solely pacemaking of the heart. Sensing, pacing, resynchronization, overstimulation and defibrillation are just some of the functions that actual devices can cover. And not only is the heart dependant on pacemaking cells; the urinary tract, the central nervous system and the blood pressure is controlled to a certain extent by endogenous pacemakers. However, one has to be careful to find the correct indication before device implantation. In addition, complications such as infections need to be minimised. It should be noted that some diagnostic or therapeutic procedures cannot be performed when a person carries an electrical device. Taken together, a correctly functioning device can improve the quality of life substantially. New devices, beside cardiac pacemakers, are currently under investigation. In order to treat arterial hypertension various strategies were developed. Besides renal nerve ablation, baroreceptor stimulation is one approach to reduce the sympathetic nerve activity. Similar to a cardiac pacemaker, an electrical device stimulates the glomus caroticus to feed back to the central nervous system in order to re-adjust the elevated blood pressure. X Preface In this book, through eleven chapters different aspects of pacemakers –functions and interactions were reviewed. In addition, various areas of application and the potential side effects and complications of the devices were discussed. Dr. med.
