Enlargement of the cardiac contractile cells results in better function of the heart.

A positive test in the patient’s blood would indicate the death of ____________________________ (cell type).

Smooth muscle also relies on calcium, but this calcium must bind to _____________________ to activate Myosin Light Chain Kinase (MLCK), which subsequently phosphorylates the myosin to generate a contraction.

A patient treated with calcium channel blockers will have a faster heart rate.

List all waves, intervals and segments of an ECG wave. Include the normal time range for each interval and segment.
