The alternative or augmentation of failing human organs with man made units and structures has been an incredible aspect in healthiness take care of numerous many years. Such units as kidney dialysis to enhance failing kidneys, synthetic center valves to interchange failing human valves, cardiac pacemakers to reestablish general cardiac rhythm, and middle support units to enhance a weakened human middle have assisted hundreds of thousands of sufferers within the past 50 years and provides lifesaving know-how for tens of millions of sufferers every year. major advances in those biomedical applied sciences have continuously happened in this interval, saving a variety of lives with innovative applied sciences. every one of those man made organ structures can be defined intimately in separate sections of this lecture.

Note the shocking coil which surrounds the pacing lead. However, if the defibrillator were placed deeper within the body, then the amount of current necessary to defibrillate the heart is far less. As a result, the device is far smaller. For those patients who may require defibrillation on a regular enough basis, an implantable version can be placed in the same site as a cardiac pacemaker—below the collarbone with the leads threaded through a vein toward the heart.

PACs and PVCs are readily observed as added waves within the ECG. An ectopic or premature atrial beat produces an added P wave within the standard ECG waveform. A PVC produces an added R wave or QRS segment within the normal ECG waveform. Repeated PAC or PCV events may indicate a serious condition that will require intervention. Fibrillation is caused when the heart muscle begins to quiver, or fibrillate, continually and cannot contract normally. When a heart is in a state of fibrillation, there is no synchronization between the atria and the ventricles, nor any standard heart beat/contraction.

As a result, the device is far smaller. For those patients who may require defibrillation on a regular enough basis, an implantable version can be placed in the same site as a cardiac pacemaker—below the collarbone with the leads threaded through a vein toward the heart. For those patients who require frequent cardiac pacing, but are also less frequently susceptible to ventricular fibrillation, then a combination unit of pacemaker and implantable cardioversion device (ICD) is implanted as shown in Figure 46.
