Relative to skeletal muscle the absolute refractory period o

Relative to skeletal muscle, the absolute refractory period of myocardial cells is: shorter the same length longer myocardial cells do not have an absolute refractory period, they only have a relative refractory period

Solution

The myocardial cells have refractory period longer than skeletal muscles due to slow inward current by voltage gated L type Ca⁺² channels. So, the correct answer is option C.
