Go through the following statements (i) Vagus nerve decreases the rate of impulse formation from the SA node and its conduction (ii) As the human heart is myogenic in nature, the rate of formation and conduction of cariac impulse cannot be changed by the action of nerves (iii) The end of T-wave in ECG marks the end of systole.

During joint diastole , tricuspid and bicuspid valves are open and the semilunar values are closed. III. The first heart sound (lub) is associated with the closure of the tricuspid and biscuspid valves whereas the second heart sound (dub) is associated with the closure of the semilunar valves . IV. Neural signals through the sympathetic nerves can increases the rate of hearbeat, the strength of ventricular contraction and thereby the cardiac output.
