What makes it impossible for myocardium to go into tetany?

Question

Quizplus · Accepted Answer

The absolute refractory period makes it impossible for myocardium to go into tetany by preventing it from being able to respond to a new stimulus until the previous contraction is completed. This allows the heart to maintain a regular rhythm and prevent potentially dangerous arrhythmias. Automaticity, cardiac myofibrils, and intercalated discs are important components of cardiac muscle function but do not directly prevent tetany.
