Biomedical electric devices provide great assistance for health and life quality. However, their maintainable need remains a serious issue the restricted duration of energy storage. Therefore, scientists are investigating alternative technologies such as nanogenerators that could harvest mechanical human heart to act main source pacemaker. Cardiac contraction is not circulation; it utilizes bod...

This paper describes a low power analogue VLSI neural network called Wattle. Wattle is a 10:6:4 three layer perceptron with multiplying DAC synapses and on chip switched capacitor neurons fabricated in 1.2um CMOS. The on chip neurons facillitate variable gain per neuron and lower energy/connection than for previous designs. The intended application of this chip is Intra Cardiac Electrogram clas...

The right ventricular (RV) apex has been the standard pacing site since the development of implantable pacemaker technology. Although RV pacing was initially only utilized for the treatment of severe bradyarrhythmias usually due to complete heart block, today the indications for and implantation of RV pacing devices is dramatically larger. Recently, the adverse effects of chronic RV apical paci...

Permanent pacemaker implantation is an established mode of life saving therapy for patients with symptomatic bradycardia. As the human population is aging world-over, the need for pacemakers are also increasing. Reviewing the results of the 2001 World Survey on Cardiac Pacing and Implantable Cardioverter Defibrillators (Table 1), it is evident that not all patients who require pacemakers are re...

A 73-year-old white male with a history of coronary artery disease, congestive heart failure, diabetes mellitus, and pacemaker/implantable cardioverter defibrillator placement presented to the emergency department with a chief complaint of abnormal laboratory tests. On arrival, he complained of nausea, vomiting, diaphoresis, and shortness of breath. Physical examination revealed pulmonary rales...

Introduction In cases of patients who have contraindications to transvenous pacing leads but still require pacing, surgically placed epicardial pacing leads are often used. If such a patient warranted implantable cardioverter-defibrillator (ICD), a subcutaneous ICD (S-ICD) system would be ideal from the standpoint of avoidance of transvenous leads, but devicedevice interaction with the epicardi...
