# Wellens Syndrome Corollaries: A Call for Definition with a Case Series

## TL;DR

This paper discusses variations in Wellens syndrome ECG patterns and suggests expanding the definition to include new cases for timely treatment.

## Contribution

The paper introduces the concept of 'Wellens corollaries' to broaden the ECG criteria for diagnosing Wellens syndrome.

## Key findings

- Three cases showed Wellens waves in leads V3 and V4 but not V2.
- Wellens waves in two contiguous leads from V1–V6 should be considered corollaries.
- A consensus on updated inclusion criteria for Wellens syndrome is needed.

## Abstract

First described in 1982, the Wellens wave is an electrocardiographic (ECG) finding indicative of a critical lesion of the left anterior descending artery. These T-wave findings are classically found in ECG leads V2 and V3, although they may extend into the lateral leads V4–V6.

We present three cases of patients with Wellens waves that were found only in leads V3 and V4 and did not include V2.

We suggest that the classical definition of T-waves in leads V2 and V3 is not the only manifestation of Wellens waves to indicate pathology. Wellens waves found in two contiguous leads in leads V1–V6 can be considered Wellens corollaries, thereby requiring the same emergent treatment as classical Wellens syndrome. We also recognize the need for a consensus on the inclusion criteria of Wellens syndrome, particularly the laboratory and ECG findings that define the disease.
