Final answer:
The correct answer is that Ventricular Fibrillation caused by R-on-T Phenomenon is a life-threatening arrhythmia, which can lead to brain death if not treated promptly with defibrillation to restore a normal heart rhythm.
Step-by-step explanation:
The correct statement about Ventricular Fibrillation resulting from R-on-T Phenomenon is C) Ventricular Fibrillation caused by R-on-T Phenomenon is a life-threatening arrhythmia. Ventricular fibrillation occurs when the heart beats in an uncontrolled manner, which severely hampers its ability to pump blood effectively. The R-on-T phenomenon can trigger this by allowing a premature ventricular contraction to occur on the T wave of the preceding beat, potentially leading to an abnormal, and often erratic, heart rhythm. If left untreated, ventricular fibrillation can lead to brain death within minutes. Defibrillation, which involves delivering an electrical shock to the heart, is typically the most effective treatment to reestablish a normal sinus rhythm and cease the fibrillation.
