Pacemakers have been available for 50 years, and implantable cardiac defibrillators for 25. Clear indications for each have been established on the basis of data from randomized clinical trials (RCTs). ⋯ Pacemakers and implantable defibrillators are well-established electrotherapeutic devices that are highly effective and have only rare complications.

The elderly need strength training more and more as they grow older to stay mobile for their everyday activities. The goal of training is to reduce the loss of muscle mass and the resulting loss of motor function. The dose-response relationship of training intensity to training effect has not yet been fully elucidated. ⋯ Progressive strength training in the elderly is efficient, even with higher intensities, to reduce sarcopenia, and to retain motor function.
