In AV sequential pacing, which ventricles receive pacing signals?

• A. Only the right ventricle
• B. Only the left ventricle
• C. Both ventricles
• D. Neither ventricle

Answer: (C)

In AV sequential pacing, the pacing system sends electrical signals in a coordinated manner to stimulate both the left and right ventricles of the heart. This approach ensures that the ventricles contract in synchrony, which is crucial for maintaining effective blood flow and optimal heart function. By activating both ventricles, AV sequential pacing helps mimic the natural physiological pacing of the heart, allowing for improved efficiency in the heart's pumping action.

In clinical practice, this type of pacing can be particularly beneficial for patients with heart conditions that affect the electrical conduction system. By pacing both ventricles, it allows for better management of heart failure and can improve symptoms related to an ineffective heart rhythm. This simultaneous activation is essential for optimizing cardiac output and maintaining hemodynamic stability.
