During radiofrequency energy delivery, the patient developed ventricular fibrillation requiring emergent cardioversion. Electrogram interrogation showed that the CIED switched to noise reversion mode during ablation. The consequent asynchronous pacing resulted in a paced QRS landing on an intrinsic T wave, ...
Finally, the third route towards target waves is realized when the frequency of the pacemaker is much higher than that characterizing the oscillations of ... LL Jiang,T Zhou,M Perc,... - 《New Journal of Physics》 被引量: 64发表: 2009年 Effects of Radiofrequency Catheter Ablation on Patie...
8). To further explore the pacing efficiency for PM in animals, complete atrioventricular block (AVB) was induced by radiofrequency ablation (Fig. 3f). Figure 3g shows the electrocardiogram (ECG) before and after atrioventricular node ablation in a swine model. The heart rate decreased from 96...
Introduction : Long-term outcome of radiofrequency ablation (RFA) for atrial fibrillation (AF) is difficult to assess. This study sought to evaluate variou... DP Zipes - 《Circulation》 被引量: 181发表: 1995年 Polyether polyurethanes for implantable pacemaker leads Two variations of a commerciall...
31 Permanent heart block can also occur as a result of direct injury during cardiac catheterization, radiofrequency catheter ablation, and other intracardiac manipulations; however, this is less frequent. Principles for managing heart block after catheterization are the same as those for managing heart...
Thus, the laser sheath has greatly improved success of lead extraction with an expected major complication rate of <2% and death rate of <1%. Electrosurgical Dissection Sheath Radiofrequency energy is provided at the tip of a Teflon sheath using bipolar current from two tungsten electrodes. Use ...
Radiofrequency ablationThe growing problem of endocardial lead infections and lead malfunctions has increased interest in percutaneous lead-removal technology. Transvenous lead extraction (TLE) via simple manual traction (SMT) is the first-line therapy. When SMT is not successful, TLE from the ...
2.Impact of radiofrequency catheter ablation for atrial fibrillation in patients with pacemakers;心房颤动导管射频消融对心脏起搏器安全性影响的临床研究 3.Clinical analysis of preschool children after implantationg of artificial cardiac pacemakers;学龄前儿童植入永久心脏起搏器的研究 ...
The limitations of current pacemakers together with the role of adjunctive techniques such as radiofrequency (RF) ablation of the atrioventricular node and coronary sinus pacing are also reviewed. Current ongoing randomized trials of DDD pacing in hypertrophic cardiontyopathy will resolve many issues, ...
The flow dynamics of crystal-rich high-viscosity magma is likely to be strongly influenced by viscous and latent heat release. Viscous heating is observed ... P Samet,W Jacobs,WH Bernstein - 《American Journal of Cardiology》 被引量: 30发表: 1963年 Radiofrequency catheter ablation versus modifi...
