Which monitoring method is used to observe for dysrhythmias after CABG?

• A. Telemetry monitoring
• B. Pulse oximetry only
• C. BP cuff measurements only
• D. Glucose monitoring

Answer: (A)

After CABG, the heart is prone to rhythm problems, especially atrial fibrillation, which can occur suddenly and affect how well the heart pumps. Telemetry provides continuous ECG monitoring, so the care team can see the heart’s rhythm in real time, detect any dysrhythmias promptly, and respond quickly with appropriate treatments or adjustments.

Pulse oximetry mainly tracks oxygen saturation (and sometimes pulse rate) but does not show the heart’s electrical activity. BP cuff measurements give intermittent blood pressure readings, not rhythm information. Glucose monitoring relates to blood sugar, not cardiac rhythm. Because identifying rhythm disturbances is critical after heart surgery, continuous telemetry is the monitoring method used.
