What is a common indicator of poor cardiac output in telemetry readings?

• A. High blood pressure
• B. Frequent PVCs
• C. Bradycardia
• D. Elevated heart rate

Answer: (B)

A common indicator of poor cardiac output in telemetry readings often involves the presence of frequent premature ventricular contractions (PVCs). PVCs can be a sign that the heart is struggling to effectively pump blood, which can result in a decrease in cardiac output. When the heart is not functioning optimally, it may lead to irregularities in rhythm such as PVCs, reflecting an underlying issue with cardiac efficiency. High blood pressure is generally associated with good cardiac output since it indicates the heart is pumping adequately against systemic vascular resistance. Bradycardia, or a slower than normal heart rate, could also be associated with decreased cardiac output; however, it is not universally indicative of poor performance, as in some cases, individuals can have normal cardiac output with bradycardia. Elevated heart rate often suggests an increase in cardiac output as the body may be compensating for other issues. Thus, frequent PVCs serve as a clearer and more direct indicator of potential troubles with cardiac output, making it a significant marker to monitor in telemetry.
