Frequent PVCs can potentially lead to which outcome for the heart?

Frequent premature ventricular contractions (PVCs) can disrupt the normal rhythm of the heart, leading to a decrease in cardiac output. This occurs because PVCs can cause inefficient heartbeats, potentially leading to a reduction in the amount of blood that is ejected from the heart during each contraction. When the heart is not able to pump effectively, it may struggle to meet the body's demands, resulting in decreased cardiac output. Over time, this can contribute to heart failure if the frequency and severity of the PVCs are significant enough to impact overall cardiac function.

Moreover, the heart relies on a regular rhythm for optimal performance, and disturbances such as frequent PVCs can lead to abnormal heart function and symptoms, including palpitations. While some may only experience palpitations, the underlying effects of PVCs on cardiac output and potential progression to heart failure are critical outcomes to consider in patients with this arrhythmia.
