All are true about Right ventricular infarct EXCEPT:
**Core Concept**
Right ventricular infarction occurs when the blood flow to the right ventricle is blocked, typically due to a blockage in the right coronary artery. This can lead to **ischemia** and **necrosis** of the right ventricular wall. The right ventricle is more susceptible to infarction due to its thinner wall compared to the left ventricle.
**Why the Correct Answer is Right**
Since the options are missing, let's discuss the general principles. In right ventricular infarction, the **right coronary artery** is often involved, and patients may present with signs of right heart failure, such as **jugular venous distension** and **hypotension**. The **inferior wall of the left ventricle** is also often involved, as the right coronary artery supplies both the right ventricle and the inferior aspect of the left ventricle.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific option, we cannot determine why it is incorrect.
**Option B:** Similarly, without the text of Option B, its incorrectness cannot be explained.
**Option C:** The same applies to Option C, as the text is missing.
**Option D:** Option D's incorrectness also cannot be discussed without its content.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that right ventricular infarction often presents with **cardiogenic shock** and **arrhythmias**, and the diagnosis can be suggested by **ST-segment elevation** in the right precordial leads (V1-V4) on an electrocardiogram.
**Correct Answer:** D. No specific answer can be provided without the question options.
