Objective To observe the Electrocardiogram （ECG） and clinical characteristics of patients with metabolic syndrome （Met S） and early repolarization pattern （ERP）

who have no history of coronary heart disease and diabetes.Methods A total of 813 patients with Met S

but without a history of coronary heart disease and diabetes

admitted to our hospital from October 1

2015 to October 1

2017 were selected.The definition of Met S meets National Cholesterol Education Program （NCEP） st

andards.ERP is defined as QRS notching or slurring in two consecutive leads（except leads V

with its amplitude≥0.1mV

with or without ST segment elevation.Results A total of 813 patients with Met S were enrolled

110 （13.5%） patients had ERP[ERP（+）

]

on their ECG

and 703 （86.5%） patients had no ERP[ERP（-）

]

.The average age of the patients was 43.51±5.19 （18-82） years old.There was no significant difference in the general conditions of the two groups of patients.In ERP （+） patients

46 cases （41.9%） of ERP distributed in inferior leads

17 cases （15.5%） in inferior wall and anterior precordial leads

and 24 cases （21.8%） in lateral leads （I

13cases （11.8%） in the lateral and anterior precordial leads

） leads.Among them

7 subjects （6.4%） had ERP amplitude≥0.2mV

which appeared in the inferior wall leads

or inferior wall and anterior precordial leads

with the horizontal ST segment.Both groups of patients underwent 24-hour Holter monitoring

and no polymorphic ventricular tachycardia or ventricular fibrillationwas recorded.Conclusions In patients with Met S

ERP is mainly distributed in inferior leads

inferior leads and precordial leads.Some patients have significant increase of ERP amplitude.However

the occurrence of malignant ventricular arrhythmias

has not been recorded.
