Some more “bad news” for people with early repolarisation syndrome

Posted Apr 04 2010 9:16am

ERS -Early repolarisation syndrome  is known as a   benign ECG finding  for  many decades  .Now it  is beginning to look dangerous as evidence is accumulating  it may have a link with ventricular arrhythmias.

ERS represents complex changes in  ionic movements during  cardiac repolarisation . (To be specific , it is due to a functional gain of  K + ionic channels during phase 3 of action potential).Generally this is a very benign condition. But , what concern us is ,  it can predispose to ventricular arrhythmias when these patients are confronted with ischemia .

When repolarisation occur early it indirectly shorts the QT interval .We know QT interval is a notorious period in human ECG as both a short and long (<320ms, > 460ms)  can be dangerous.

Is ERS a marker for potential cause for primary VF ?
