Ecg Coronary Artery Disease

In a standard ECG, which one of the following alphabets is the correct representation of the respective activity of the human heart?

1. R-repolarisation of ventricles

2. S-start of systole

3. T-end of diastole

4. P-depolarisation of the atria

The diagram given here is the standard ECG of a normal person, The P - wave represents the:

Match the Column I and Column II:

	Column I		Column II
(a)	P-waves	(i)	Depolarisation of ventricles
(b)	QRS complex	(ii)	Repolarisation of ventricles
(c)	T-wave	(iii)	Coronary ischemia
(d)	Reduction in the size of T-wave	(iv)	Depolarisation of atria
		(v)	Repolarisation of atria

Select the correct option:

Options:	(a)	(b)	(c)	(d)
1.	(ii)	(iii)	(v)	(iv)
2.	(iv)	(i)	(ii)	(iii)
3.	(iv)	(i)	(ii)	(v)
4.	(ii)	(i)	(v)	(iii)

Match List-I with List-II

	List-I		List-II
A.	P-wave	I.	Beginning of systole
B.	Q-wave	II.	Repolarisation of ventricles
C.	QRS complex	III.	Depolarisation of atria
D.	T-wave	IV.	Depolarisation of ventricles

Choose the correct answer from the options given below:

Options:	A	B	C	D
1.	I	II	III	IV
2.	III	I	IV	II
3.	IV	III	II	I
4.	II	IV	I	II

Match List-I with List-II:

	List-I		List-II
A.	P wave	I.	Heart muscles are electrically silent
B.	QRS complex	II.	Depolarisation of ventricles.
C.	T wave	III.	Depolarisation of atria.
D.	T-P gap	IV.	Repolarisation of ventricles.

Choose the correct answer from the options given below:
1. A-III, B-II, C-IV, D-I
2. A-II, B-III, C-I, D-IV
3. A-IV, B-II, C-I, D-III
4. A-I, B-III, C-IV, D-II
