Modern Perspectives on Numerical Modeling of Cardiac Pacemaker Cell
.: Cardiac pacemaking is a complex phenomenon that is still not completely understood. Together with experimental studies, numerical modeling has been traditionally used to acquire mechanistic insights in this research area.

Electrosurgery and cardiac pacemakers
There are two basic types of cardiac pacemakers: (1) Fixed-rate pacemakers stimulate the heart at a regular rate independent of the intrinsic heart rate. (2) Demand pacemakers sense the heart's spontaneous rhythm. They are more commonly used because they are noncompetitive with the heart.

Abstract The fact that prolonged electrical treatment for complete heart block and other arrhythmias is possible cannot be disputed. There is, however, a continuing need to define the parameters of long-term stimulation in precise terms which include current, voltage, stimulus duration, electrode surface area, and a specific need to relate these to ...

Midterm Follow-up and Outcome of Pacemakers in Children: A Single Center Experience [PDF]
Background: Pacemaker implantation is an effective life-long treatment in patients with atrioventricular block to generate a reliable heartbeat. Choosing between epicardial and endocardial (trans-venous) techniques in children is based on the cardiac ...

A self-assembled implantable microtubular pacemaker for wireless cardiac electrotherapy
The current cardiac pacemakers are battery dependent, and the pacing leads are prone to introduce valve damage and infection, plus a complete pacemaker retrieval is needed for battery replacement.

Feasibility of physiological pacing rate in cardiac resynchronization therapy
Aims Although cardiac resynchronization therapy (CRT) improves functional capacity in heart failure patients, a blunted heart rate (HR) response remains after treatment.

Minithoracotomy as the primary alternative for left ventricular lead implantation during cardiac resynchronization therapy: Can the cardiac surgeon reduce the number of nonresponders [PDF]
Introduction/Objective. Numerous anomalies of the cardiac venous system prevent the optimal endovascular implantation of the left ventricular (LV) lead in more than 15% of patients with indication for cardiac resynchronization therapy (CRT).
