From the Guidelines
The presence of "bunny ears" on an electrocardiogram (ECG) is a strong indicator of Brugada syndrome, a serious cardiac condition that can lead to sudden cardiac death. This characteristic pattern is seen as an elevated ST segment (>2 mm) followed by a negative T wave in leads V1-V3, creating a shape resembling rabbit ears 1. The diagnosis of Brugada syndrome is primarily based on the ECG findings, and it is essential to recognize this pattern promptly as it indicates a high risk of ventricular fibrillation and sudden death, especially in young, otherwise healthy individuals. If this pattern is observed:
- Immediately consult a cardiologist for confirmation and further management.
- The patient may need genetic testing and possibly an implantable cardioverter-defibrillator (ICD) for prevention of sudden cardiac death.
- Avoid medications that can exacerbate Brugada syndrome, including certain antiarrhythmics, psychotropics, and anesthetics. It is crucial to note that the presence of "bunny ears" on an ECG is a significant finding that requires prompt attention and management to prevent potentially life-threatening complications.
From the Research
ECG Interpretation
The presence of 'bunny ears' on an electrocardiogram (ECG) is not directly mentioned in the provided studies. However, we can look at the general information provided about ECGs and their interpretation:
- The ECG is a primary clinical tool for assessing cardiac electrical events, providing global and regional information on rate, rhythm, and electrical conduction, as well as changes in electrical activity associated with cardiac disease 2.
- In the context of pet rabbits, a study established reference ranges for normal pet rabbit ECGs, including heart rate, P wave duration and amplitude, P-R interval, QRS complex duration, R wave amplitude, Q-T interval, and T wave amplitude 3.
Relevance to 'Bunny Ears'
There is no direct information provided in the studies about the presence of 'bunny ears' on an ECG. The term 'bunny ears' is not mentioned in the context of ECG interpretation or cardiac electrophysiology in the provided studies 2, 3.
- A study on the anatomy of the rabbit inner ear using computed tomography and magnetic resonance imaging provides detailed information on the inner ear structure, but does not relate to ECG interpretation or the presence of 'bunny ears' on an ECG 4.
