QUIZ ON DISORDERS OF CARDIOVASCULAR AND RESPIRATORY SYSTEM

Which investigation is most useful to evaluate heart rhythm abnormalities?

• Chest X-ray

• ECG

• CT chest

• Cardiac MRI

ST-segment elevation on ECG is most suggestive of:

• Stable angina

• Non-ST elevation myocardial infarction

• Acute ST-elevation myocardial infarction

• Arrhythmia

Rheumatic Heart Disease is caused by which of the following?

• Bacteria

• Viruses

• Hormonal imbalance

• immune reaction

What characteristic ECG findings are typically seen in ventricular tachycardia?

• Narrow QRS complexes

• Wide QRS complexes with regular rhythm

• Sinus P waves before every QRS

• Sawtooth flutter waves

Which of the following is not a part of the upper respiratory tract?

• epiglottis

• larynx

• trachea

• soft palette

The most common type of sleep apnea is:

• Central sleep apnea

• Obstructive sleep apnea

• Mixed sleep apnea

• Secondary sleep apnea

A patient with progressive dyspnea, non-productive cough, and restrictive spirometry findings is most likely to have

• Interstitial lung disease

• COPD

• Asthma

• Pulmonary embolism

A patient with progressive shortness of breath, dry cough, and “honeycomb lung” on HRCT most likely has

• COPD

• Pulmonary tuberculosis

• Idiopathic pulmonary fibrosis

• Pleural effusion

The gold standard test for diagnosing obstructive sleep apnea is

• Spirometry

• Overnight pulse oximetry

• Polysomnography

• Arterial blood gas analysis

A patient with chest pain shows ST-segment depression and T-wave inversion on ECG. This most likely indicates:

• Acute STEMI

• Stable angina

• Non-ST elevation myocardial infarction (NSTEMI)

• Prinzmetal’s angina
