Which of the following conditions is a common cause of ventricular tachycardia?

  1. Coronary artery disease

  2. Asthma

  3. Chronic obstructive pulmonary disease

  4. Hypertension

The correct answer is: Coronary artery disease

Ventricular tachycardia (VT) is a rapid heart rhythm that originates in the ventricles, and coronary artery disease is a common underlying cause of this condition. This disease can lead to ischemia, which can impact the electrical system of the heart, creating an environment where abnormal rhythms such as VT can develop. In patients with coronary artery disease, the heart muscle may become damaged or scarred from previous heart attacks, which increases the risk of arrhythmias. Other conditions listed, such as asthma and chronic obstructive pulmonary disease, primarily affect the respiratory system and do not directly cause ventricular tachycardia. While hypertension can affect heart health, its primary effects include increasing the workload on the heart rather than causing the electrical disturbances that lead to VT. Thus, the relationship between coronary artery disease and the mechanisms that lead to ventricular tachycardia makes it the most relevant condition in this context.
