Abstract

Disclosed are devices, systems, and methods, including a device that includes a dynamically configurable pulse generator to generate one or more electrical pulses with one or more adjustable attributes, the one or more pulses to be applied to a load (e.g., cardiac tissue) through electrodes. The configurable pulse generator is operable to be reconfigured after generating at least one of the one or more pulses. The device also includes a controller to dynamically configure the pulse generator to generate the one or more electrical pulses. The device may further include at least one sensor to measure at least one characteristic (e.g., impedance) associated with the load (e.g., the cardiac tissue of a patient). The pulse generator may be adapted to generate the one or more pulses with the attributes determined based, at least in part, on the measured at least one characteristic associated with the load.
