==ECG markers of increased risk of ventricular arrhythmias in ICD patients==
In a recent study several ECG risk markers were found to be associated with appropiate therapy in ICD patients<cite>Shi</cite>:
* depressed heart rate variability (HRV) [HR 2.7]
* BBB with large QRS dispersion of > 39 msec (difference between maximal and minimum QRS across 12 leads) [HR 2.9]
* Reduced maximal T wave amplitude (<0.4 msec in patients without BBB) [HR 3.8]
* History of atrial arrhythmias [HR 2.3]
