Which one of the following statements are correct ?
(A) The duration of cardiac cycle is 0.8sec seconds. During cardiac cycle, each ventricle pumps out approximately 70ml of blood, which is called the stroke volume.
(B) The stroke volume multiplied by the heart rate gives the cardiac output, which averages 5 litres in healthy individual.
(C) The cardiac output of athlete will be lower than of an ordinary man.
(D) During cardiac cycle, only one heart sound is produced which can be easily heard through instrument stethoscope.
(E) The first heart sound (dub) is associated with the closure of tricuspid and bicuspid valves and the second heart sound (lub) is associated with closure of semilunar valves.
(F) ECG is a graphical representation of electrical activity of the heart during cardiac cycle.
(G) To obtain a standard ECG, a patient is connected to the machine with 3 electrical leads. One to each wrist and one to left ankle.
(H) The P-wave in ECG represents excitation or polarization of the atria.
(I) The QRS complex of electrocardiogram represents the depolarization of the ventricle.
(J) The T-wave of electrocardiogram represents repolarization and end of T-wave marks the end of diastole.
(K) Blood pumped by left ventricle enter the aorta whereas blood pumped by right ventricle enters pulmonary artery.
