There are several factors that contribute to the reduction in efficiency in cardiac dysrhythmias:

Irregular heartbeats: Irregular heartbeats, also known as arrhythmias, prevent the heart from beating in a coordinated and efficient manner, reducing its ability to pump blood effectively.

Abnormal electrical impulses: In cardiac dysrhythmias, the electrical impulses that regulate the heartbeat are disrupted, leading to irregular and inefficient heartbeats.

Decreased cardiac output: The heart's ability to pump blood is reduced in cardiac dysrhythmias, leading to decreased cardiac output and reduced perfusion.

Blood clots: Blood clots that form as a result of cardiac dysrhythmias can obstruct blood flow, reducing perfusion.

Tissue hypoxia: Reduced perfusion can lead to tissue hypoxia, where the tissues receive insufficient oxygen, causing cellular injury and death.

Heart failure: In severe cases, cardiac dysrhythmias can lead to heart failure, where the heart can no longer pump blood effectively, resulting in reduced perfusion to the body's organs and tissues.
