How do you calculate excitation frequency?

Excitation frequency can be calculated as the reciprocal of the excitation period, which is the time interval between two consecutive excitations. The formula is: Excitation frequency = 1 / Excitation period. Alternatively, if you know the excitation waveform (e.g., sine wave), you can determine the excitation frequency from the period of that waveform.


How do t-tubules contribute to the excitation-contraction coupling process in cardiac muscle?

T-tubules in cardiac muscle help transmit electrical signals deep into the muscle cells, allowing for synchronized contraction of the heart muscle. This process, known as excitation-contraction coupling, ensures that the heart beats effectively and efficiently.
