Batteries for Health-Related Applications

Preliminary studies undertaken by the author on the batteries required for medical applications and other medical diagnostic procedures reveal that these batteries must meet stringent performance specifications, such as accuracy, dependability, portability, reliability, and long service life. This section describes the performance 

1 Battery Requirements for Cardiac Rhythm-Detection Applications 

According to heart specialists, four distinct types of medical devices can be used to treat cardiac diseases, namely pacemakers, cardioverters, defibrillators, and left-ventricular assist devices. In addition, the total artificial or mechanical heart needs to be powered by batteries with an emphasis on reliability, safety, and OCV with no electrical surges and voltage fluctuations. Generally, cardiac pacemakers are prescribed by heart specialists when the cardiac rhythm is too slow or when the patient has an abnormal heart beat. This device is implanted in the patient s chest. The implanted pacemaker detects the slow heart rate and sends electrical impulses to stimulate the heart muscle. An electrical signal from the muscle is fed back to the device to make appropriate corrections in the stimulation parameters, which will normalize the heart rate within a hundred microseconds or so.
