From VVI to DDD pacemakers: Glossary of terms and normal functions,sease Resources (ICHD) as a standardized means for identifying the functional operation of a pulse generator, irrespective of model number, trade name or complexity. In this initial ICHD code, the first letter indicates the paced chamber(s) and the second letter the chamber(s) being sensed while the

A practical guide to the interpretation of DDD pacing electrocardiograms,ulse generator operates with sensing and stimulation at both the atrial and ventricular levels depending on the presence or absence of spontaneous cardiac activity in relation to the programmed intervals. It is impossible to give a complete survey of all electrocardiographic appearances. This chapte

Rate-adaptive cardiac pacing,tive or rate-responsive device. The importance of increased heart rate for augmenting cardiac output with exercise has been clearly documented , and the benefits of rate-adaptive systems over fixed rate pacemakers have been documented repeatedly in terms of exercise tolerance, symptomatology, and

Dual chamber rate responsive (DDDR) pacing: ventricular versus atrial timing,ntly, cardiac output. The addition of rate responsiveness to DDD pacemakers may almost completely mimic normal heart function in patients in whom the sinus node is not a suitable indicator of physiologic heart-rate modulation. As DDD pacemakers come in widespread clinical use, new electrocardiograph

Antitachycardia Pacing,cts are common and the therapy is sometimes worse than the disease. A lot of attention has recently been given to proarrhythmic side effects of antiarrhythmic drugs . Furthermore, when we are dealing with a disease with paroxysmal behaviour, drug therapy poses additional problems. . It is a

Electrical treatment of tachycardias,since SVT usually have a good prognosis, problems occurring during long-term follow-up, especially the adverse effects of drugs, may lead to the use, in some cases, of nonpharmacological therapies. Finally, some SVT are definitively resistant to any drug combination, and one of the 3 possible nonpha
