MY APPROACH to Early Repolarization Syndrome

Since 2008, the ER definition has shifted away from this traditional focus on ST-segment elevation and focuses instead on J wave or QRS notching or slurring. [...]the modern definition of ER is J wave or an end QRS notch or slur on the downslope of a prominent R wave with J-point elevation >=0.1m...

Description
Summary:Since 2008, the ER definition has shifted away from this traditional focus on ST-segment elevation and focuses instead on J wave or QRS notching or slurring. [...]the modern definition of ER is J wave or an end QRS notch or slur on the downslope of a prominent R wave with J-point elevation >=0.1mV in 2 or more contiguous leads of the 12-lead ECG, excluding leads V1-V3. To avoid confusion, my approach uses the modern ER definition. [...]the term "early repolarization syndrome" should be reserved for ER patterns associated with vulnerability to polymorphic ventricular tachycardia (VT) and ventricular fibrillation (VF) leading to sudden cardiac death (SCD).
