Final answer:
The statement about ventricular fibrillation causing the myocardium to quiver like a bowl of Jell-O is true. Ventricular fibrillation is a life-threatening emergency where the heart quivers instead of pumping due to erratic electrical patterns, and defibrillation is the appropriate treatment to restore normal heart rhythm.
Step-by-step explanation:
True or False: With ventricular fibrillation, the entire myocardium is quivering similar to a bowl of Jell-O when shaken. This statement is true. Ventricular fibrillation is a condition where the heart beats in a rapid, erratic electrical pattern, causing the muscle fibers of the ventricles to quiver ineffectively instead of contracting in a synchronized manner to pump blood.
Ventricular fibrillation is indeed a medical emergency that requires immediate attention. If left untreated, it can lead to brain death due to the lack of effective blood pump by the ventricles. The treatment for ventricular fibrillation is defibrillation, which delivers a controlled electrical shock to the heart using special paddles or pads. The purpose of the shock is to momentarily stop the heart and erase its chaotic electrical activity, allowing for the possibility of the heart's natural pacemaker to reset and establish a normal rhythm.
