Wireless sensor networks consist of sensor nodes with sensing and communication capabilities. Efficient aggregation of data collected by sensors is crucial for a successful application of wireless sensor networks (WSNs). Both minimizing the energy cost and reducing the time duration of data aggregation have been extensively studied for WSNs. Algorithms with(More)
We studied 109 patients who were subjected to dobutamine stress echocardiography (DSE) for preoperative cardiac risk assessment before undergoing elective primary hip and knee arthroplasty. Patients were selected for DSE based on several criteria. There were 16 patients with history of ischemic heart disease and 93 patients without. Seven of the 93 patients(More)
Fascicular VT and RVOT tachycardia are sometimes difficult to induce by programmed electrical stimulation (PES), despite pharmacologic provocation. In such instances, catheter mapping is hampered and efficacy of catheter ablation is difficult to judge. The study included nine patients who presented with incessant idiopathic VT and were directly taken to the(More)
