What might increased workload due to systemic vascular resistance necessitate?

Increased workload due to systemic vascular resistance often leads to a need for modification of pacing settings. This is because when the heart encounters increased resistance, it must work harder to maintain adequate cardiac output. If the pacing settings are not adjusted accordingly, the heart may not be able to meet the metabolic demands of the body effectively.

Modifying pacing settings can involve changing the pacing rate or the mode of pacing to optimize heart function and support circulation under the increased workload. Proper adjustments in these settings ensure that the heart can respond appropriately to the physiological demands placed upon it, which is essential for patient stability and overall cardiac efficiency.
