Dual-chamber rate-modulated (DDDR) pacing is a mode that is programmed into a pacemaker and recommended for patients with atrioventricular block and sinus node dysfunction. DDDR …

Recommendations include DDD pacing for complete heart block and when there is a requirement for atrioventricular synchrony over a wide range of rates—for example, in young or active …

Dual-chamber system The most common two-chamber system is DDD, which implies pacing in the atria and ventricles, sensing in the atria and ventricles, and the ability be inhibited or …

During the past one decade Cardiac Resynchronization Therapy [CRT] using Biventricular [Bi V] pacing has emerged as a promising technique in improving the quality of life, exercise …

The second letter indicates the chamber of the heart being sensed or monitored. The third letter indicates how the device should respond when it senses a cardiac event (T = Triggered; I = …

The heart rate increased from 60 to 175 beats/min, blood pressure from 140/90 to 170/90 mm Hg, and cardiac index from 3.2 to 11.4 liters/min per m2. After a rest period and return of the …

Intermittent ventricular undersensing in the device with MVP feature turned on caused repetitive mode switches between AAI and DDD mode. This report shows unexceptional occurrence of …

Relatively cost effective Dual chamber pacing [DDD] with right atrial and isolated left ventricular pacing [RA-LV] can be a good alternative. Keywords: Bi ventricular; Cardiac resynchronization …

The basic principle of the DDD mode is to synchronize ventricular pacing with atrial sensing (triggered functioning) or pacing. Spontaneous atrial or ventricular activity respectively inhibits …
