Objective To investigate indications,pacing modes,pacing parameters and postoperative complications of pacemaker implantation for patients aged 80 years or over.Methods Patients were recruited on a continuous basis and were assigned into two groups,with 112 patients in the very elderly (80-90 years old) group and 484 patients in the elderly (60-79 years old) group,which served as the control.Follow-up observations with the two groups were conducted concerning indications,mode selection,pacing parameters and postoperative complications.Results Compared with the control group,the very elderly group showed:1) a higher rate of coronary heart disease (58cases vs.163 cases or 51.8% vs.33.7% ; x2 =12.78,P<0.01) ; 2) more single-chamber pacemaker implantations (63 cases vs.217 cases or 56.3% vs.44.8%; x2=4.76,P<0.05) and fewer dual-or multi-chamber pacemaker implantations (49 cases vs.267 cases or 43.8% vs.55.2% ; x2 =4.76,P<0.05) ; 3) a higher rate of double bundles branch block (19 cases vs.31 cases or 17.0% vs.6.4% ; x2=13.20,P<0.01); 4) a higher rate of postoperative acute cerebral infarction (x2 =8.34,P<0.01) ; and 5) increased ventricular [(0.78±0.24)V vs.(0.55±0.16)V,P<0.05]and atrial [(1.07±0.22)V vs.(0.84±0.28)V,P<0.05]pacing thresholds.Conclusions Special considerations should be made when pacemaker implantation is planned for patients aged 80 or over.Pacemaker selection decisions ought to be based on a comprehensive evaluation of relevant clinical situations so that clinical benefits can be maximized.

Volume concentration determination for atmospheric krypton and xenon is very important for krypton-85 and radioactive xenon isotopes monitoring. An injection setup integrated adjustable quantity sample injection and quantitative dilution function was designed. The effects of EI source parameters on the sensitivity of MS detector were studied. The optimized values were as following: ionization energy of 70 eV, emission current of 40 mA, cathode voltage of 27 mV, focus voltage of 85 mV and lens compensation of 20 V, respectively. A GC-MS method for the determination of krypton and xenon in atmosphere without of sample pretreatment was developed. The minimal detected concentrations for krypton and xenon were 3. 3×10-8(V/V) and 2. 6×10-9(V/V). Moreover, the krypton and xenon concentrations in the ground level air around our laboratory were measured with the results of 1 . 1 × 10-6 ( V/V ) and 9 . 3 × 10-8 ( V/V ) . The related combined standard uncertainties for krypton and xenon results were 2. 38% and 3. 15%, respectively.
