Assertion : The cardiac output of an ordinary man and of an athlete is the same Reason : It is impossible to alter the stroke volume as well as heart rate.A. If both assertion and reason are true and reason is the correct explanation of assertionB. If both assertion and reason are true but reason is not the correct explanation of assertionC. If assertion is true but reason is falseD. If both assertion and reason are false |
|
Answer» Correct Answer - D The stroke volume multiplied by the heart rate (no. of beats per min.) gives the cardiac output. Therefore, the cardiac output can be defined as the volume of blood pumped out by each ventricle per minute and average `5000` mL or `5` litres in a healthy individual. The body has the ability to alter the stroke volume as well as the heart rate and thereby the cardiac output. For example, the cardiac output of an athelete will be much higher than that of an ordinary man. |

Assertion : The enlarged Q and R waves indicate myocardial infarction Reason : Any deviation in the normal recording of ECG indicates possible abnormality or disease.A. If both assertion and reason are true and reason is the correct explanation of assertionB. If both assertion and reason are true but reason is not the correct explanation of assertionC. If assertion is true but reason is falseD. If both assertion and reason are false |
|
Answer» Correct Answer - B A normal electrocardiogram (ECG) is composed of P wave, a QRS wave (complex) and a T wave. The ECGs obtained from different individuals have roughly the same shape and any deviation from this shape indicates a possible abnormality or disease. For example, the enlarged Q and R wave indicate a myocardial infraction (heart attack), enlargement of the P wave indicates enlargement of the atria. T wave is flat when the heart muscles receive insufficient oxygen as in atherosclerotic heart disease. |

Read the assertion and reason carefully to mark the correct option out of the options given below: (a) If both the assertion and the reason are true and the reason is a correct explanation of the assertion (b) If both the assertion and reason are true but the reason is not a correct explanation of the assertion (c) If the assertion is true but the reason is false (d) If both the assertion and reason are false (e) If the assertion is false but reason is true Assertion : An artifical pacemaker can replace the sinoatrial node of heart. Reason : This is because, an artifical pacemaker is capable of stimulating the heart electrically to maintain its beats. |
|
Answer» Correct Answer - A An artificial pacemaker is a therapeutic instrument which is implanted in the heart of patients to generate the heart beat. A pacemaker is used when the normal heart rate of 72-80 drops down to abnormally low levels like 30-40 due to diseases or operations and threatens the life of the patient. Sometime the SA node may become damaged or defective. if then fails to generate cardiac impulses at the normal rate. the heart beats become abnormally slow and irregular and venticles fail to pump the required amount of blood. this is remedied by the chest of the patient. the artificial pacemaker stimulates the heart electrically at regular intervals to maintain its beats. thus it replaces th SA node as the originator of the cardiac impulse. |
