\"Early<\/p>\n

Early repolarization syndromeConcave upwards ST segment elevation with a notch at the end of the QRS complex (J point) or a slurring of the terminal QRS seen in lateral leads is characteristic of early repolarization syndrome (ERPS). Till recently ERPS was considered as a benign condition, only thought of in the differential diagnosis of ST elevation myocardial infarction. But a paper by Haissaguerre\u00a0 M et al in\u00a0NEJM <\/em>[1]\u00a0in 2008 brought ERPS into limelight as a potential arrhythmogenic condition. Actually the same group had highlighted on the new syndrome the previous year in the Journal of Interventional Cardiac Electrophysiology\u00a0<\/em>[2].<\/span><\/span><\/p>\n

In an article by Frederic Sacher and Michel Haissaguerre in BMH Medical Journal<\/a>\u00a0<\/em>[3], they highlighted on the need for specific definition for ERPS. They also mentioned that having an ERPS pattern is not a disease by itself. But it is crucial to give importance when there is a family history of sudden cardiac death and in patients with syncope having dramatic J point elevation and a descending\/horizontal ST segment. They mentioned that even though 5% of Caucasian population may have this ECG pattern, only 1\/2500 are at risk of ventricular fibrillation.<\/p>\n

Another article by the same group of authors has given a few ECG examples in which ventricular fibrillation occurred after an ectopic beat in those with early repolarization syndrome [4].<\/p>\n
