339342 Given below is the ECG of a normal human. Which one of its components is correctly interpreted?
supporting img

1 Peak P and Peak R together - Systolic and diastolic blood pressures
2 Peak P - Initiation of left atrial contraction only
3 Complex QRS - One complete pulse
4 Peak T - Initiation of total cardiac contraction

339358 In a standard ECG which one of the following alphabets is the correct representation of the respective activity of the human heart?

1 S-start of systole
2 T-end of diastole
3 P-depolarisation of atria
4 R-repolarisation of ventricles

339343 Choose the correct statement:
I. The T- wave in an ECG represents excitation of ventricles.
II. The sum of \(\mathrm{P}\) and \(\mathrm{T}\) waves in a given time period can determine the heartbeat rate of an individual.
III. The end of the P- wave marks the end of the systole.
IV. In a standard ECG, a person is connected to the machine using three electrical leads.

1 IV only
2 I only
3 III and IV only
4 II and only IV

339344 Which of the following cardiac events occur between Q wave and T wave on ECG?
i. Opening of bicuspid and tricuspid valves
ii. Closure of bicuspid and tricuspid valves
iii. Opening of semilunar valves
iv. Closure of semilunar valves
v. Lub sound
vi. Dub sound

339345 Statement A :
The P-wave in ECG represents the depolarization of the atria which leads to the contraction of both the atria.
Statement B :
The QRS complex represents the depolarization of the ventricles which initiates the ventricular contraction.

1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
