Drug-Induced Arrhythmias Risk in Elderly
There are intrinsic changes in the cardiac pacemaker cells and the cardiac conduction system associated with aging, which increase the propensity of the elderly population to develop chronotropic incompetence, conduction block, and bradycardia overall. Moreover, the already-at-risk elderly population is more likely to receive and is more sensitive to a variety of cardiovascular agents that may cause further bradycardia through suppression of the pacemaker activity or AV block.
