ECG of a patient with snake bite is shown below. What is the abnormality seen?
**Core Concept**
The question is referring to a specific ECG abnormality associated with a snake bite. This abnormality is related to the venom's effect on the heart's electrical activity, leading to a characteristic pattern on the ECG.
**Why the Correct Answer is Right**
The ECG abnormality seen in snake bite victims is typically a sine wave pattern, also known as a "sine wave rhythm." This occurs due to the venom's effect on the heart's electrical conduction system, specifically the sinoatrial (SA) node and the atrioventricular (AV) node. The venom can cause a blockage of the AV node, leading to a prolonged PR interval and eventually a conversion to a sine wave pattern. This pattern is a result of the heart's inability to generate a normal P wave, leading to a continuous, undulating wave.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not specified, so we'll assume it's incorrect and not relevant to the question.
* **Option B:** This option is also not specified, so we'll assume it's incorrect and not relevant to the question.
* **Option C:** This option is also not specified, so we'll assume it's incorrect and not relevant to the question.
**Clinical Pearl / High-Yield Fact**
In patients with snake bites, a sine wave pattern on the ECG is a sign of severe cardiac involvement and requires immediate medical attention. This pattern is often associated with a poor prognosis and a high mortality rate if not treated promptly.
**Correct Answer:** C. Sine wave pattern
