In which scenario is transcutaneous pacing primarily indicated?

Transcutaneous pacing is primarily indicated in cases of symptomatic bradycardia. This condition occurs when the heart beats too slowly (generally less than 60 beats per minute) and the patient experiences symptoms such as dizziness, weakness, or confusion due to inadequate blood flow. In such scenarios, immediate intervention is necessary to stabilize the patient, and transcutaneous pacing provides a rapid way to restore heart rate and improve hemodynamics.

The effectiveness of transcutaneous pacing lies in its ability to deliver electrical impulses through the skin to stimulate the heart, making it a valuable emergency treatment. It is important to note that while it can be initiated in certain other cardiac scenarios, symptomatic bradycardia specifically necessitates this intervention to alleviate symptoms and prevent potential deterioration of the patient's condition.
