Item Description: dual chamber pacemaker rate responsive ( dddr ) with appropriate atrial and ventricular bipolar steroid eluting with life warranty provision of pacing therapy for the use of the patients life- time including any no. of pulse generator replacements as clinically required ) and should have the latest technological features to provide proportionate, smooth and appropriate response of pacing rate to increased metabolic demand, should provide for atrial and ventricular pacing and sensing with choice of at least 16 modes of operation, latest technological features, appropriate safety features to avoid cross talk, optimum flexibility of programming ( including minimal av delay of 30msec or less and atrial sensitivity of 0. 2mv or less ), detailed data storage with easy retrieval and display of advanced diagnostics for ease of clinical follow up & maximal longevity. should be capable of programming for prolonging longevity and maximal cost effectiveness. should be capable of providing reliable ventricular capture with lowest battery drain so as to provide maximum longevity of the pacing system. ( preferably as an automatic feature where the pulse generator can perform a periodic threshold test and reliably verify ventricular capture and adjust ventricular pulse output parameters to minimize battery drain without compromising patient safety ). should have features for automatic management of arrhythmias ( including pacemaker mediated arrhythmias ) as well as automatic mode switching ( mode switch should be to and from ddd to ddi/ vvir, provision of rate responsive pacing after mode switch and automatic reversion to ddd after termination of mode switch triggering arrhythmias ). should have algorithms to promote intrinsic conduction. recording of atrial arrhythmia log. both atrial and ventricular channels should have provision for high energy output i.e. up to 6. 0 volts pulse amplitude and pulse width up to 1. 5ms, follow up diagnosis and rea ' a- programming should be rendered as effective as possible through provision of adequate information management systems on the programmer. the latest programmer with up dated software should be available permanently at the hospital. leads should be bipolar, steroid eluting and low profile either tined or screw. in ( 7f or smaller introducer individually ). leads should be from the same manufacturer i.e. manufactured by the same company as the pulse generator, not outsourced and marketed by one company. pulse generator and leads should be suitable for adult and pediatric patients. the manufacturers should have an established track record and presence in the market and should have facilities for simultaneous display of multiple surface ecg leads, intra cardiac electrograms, event markers; electronic calipers and for recording the same both on paper and electronic storage, media e.g. floppy disks etc. the programmer should have the latest software and should be available at all times in the hospital. the programmer should be user friendly and should provide maximum ease and efficiency of follow up assessment and automatic display of diagnostic data as required as well as follow up support at the hospital. should be approved by the us fda for intended clinical use in usa. the certificate from us- fda mentioning the validity of the period of the certificate should be submitted at the time of submission of tender. the manufacturer and supplier should have a well established track record and significant presence in the market and should provide latest programmer with appropriate software and follow up support at the hospital. the programmer should have facilities for simultaneous display of multiple surface ecg leads, intracardiac electrograms, event markers, electronic calipers, and for recording the same both on paper and in el
