What is a potential hazard of inappropriate pacing during the T wave phase?

• A. Heart rate stabilization
• B. Development of arrhythmias
• C. Increased heart contractility
• D. Pacemaker malfunction

Answer: (B)

During the T wave phase of the cardiac cycle, the heart is vulnerable to disturbances. If pacing occurs inappropriately during this phase, it can lead to the development of arrhythmias. The T wave represents the repolarization of the ventricles, and if stimulation is applied at this time, it can disrupt the normal electrical activity of the heart. This interruption can trigger various types of arrhythmias, some of which can be life-threatening. Understanding the timing of the cardiac cycle is crucial for pacing; inappropriate pacing can lead to uncoordinated contractions, potentially causing the heart to beat irregularly or even stop. This highlights the importance of careful monitoring and timing in telemetry practice to prevent these dangerous consequences.
