Question

Match the following with regard to ECG

(a)	Prolonged Q-T interval	(i)	Fast beating of heart
(b)	Tall T-wave	(ii)	Block of conduction through bundle of His
(c)	Shortened P-R interval	(iii)	Hypothyroidism
(d)	Variation in QRS interval	(iv)	Enlarged atria
		(v)	Hyperkalemia

• A. a-v, b-iv, c-ii, d-i
• B. a-ii, b-iv, c-v, d-i
• C. a-iii, b-v, c-ii, d-i
• D. a-iii, b-v, c-i, d-ii.

Answer 1

The correct option is D a-iii, b-v, c-i, d-ii.

• Hypothyroidism is caused by atrioventricular blocks and of acquired long QT syndrome.
• Tall and narrow (peaked) T wave in the electrocardiogram indicates the hyperkalemia. That can cause life-threatening arrhythmia.
• The shortened P-R interval causes the pre-excitation or AV nodal (junctional) rhythm.
• Wolff Parkinson's white syndrome, increasing age along with other common conditions such as ischemia or myocardial infarction. It can lead to damage to the AV node or the more conduction tissues such as the bundle of His.
• Variation in the QRS interval may be cause the blockage of conduction through a bundle of His.

So, the correct answer is option D.
