Generating artificial pulse

An implantable blood pump system, the system comprising:

• an implantable blood pump configured to supplement or replace a pumping function of a heart, the implantable blood pump operable in a first pump speed pattern and a second pump speed pattern;
• a controller coupled with the implantable blood pump and configured to receive a first input, and in response to receiving the first input, to transmit a signal to the implantable blood pump to transition from operating in the first pump speed pattern to operating in the second speed pattern;
• wherein the first input is indicative of a low power condition of the implantable blood pump system;
• wherein the second pattern is a constant speed mode.

• a controller coupled with the implantable blood pump and configured to receive a first input, and in response to receiving the first input, to transmit a signal to the implantable blood pump to transition from operating in the first pump speed pattern to operating in the second speed pattern;
• wherein the controller is further configured to receive a second input, and in response to the second input, to transmit a signal to the implantable blood pump to transition from operating in the second pump speed pattern to operating in the first pump speed pattern;
• wherein the first pump speed pattern comprises an artificial pulse mode and the second pump speed pattern comprises a constant speed mode.
