Missing links in IHD : What is the relationship between Ischemia & cardiac arrhythmias ?

The term Ischemic heart disease (IHD) was once very popular, but many abandoned it as it became an academic cliche.  CAD & CAHD are the other terms that are equally popular and prevalent. Stable IHD was in vogue till recently, which was again replaced by “chronic coronary syndrome’ now. Honestly, I feel the original term IHD to be restored however outdated it may look. it encompasses the entire spectrum of clinical cardiac disorders. Manifestation of Ischemia heart disease  Angina Infarction Cardiac failure Arrhythmias  Silent ischemia Sudden cardiac death  The purpose of this post is to share some thoughts on the link between Ischemia and cardiac arrhythmia.      What is the relation between  Ischemia and cardiac arrhythmia (especially VT) A.Strong relation B.Weak relation  C.No relation  D. Recurrent ischemia protects against arrhythmia. The fact that. acute Ischemia triggers primary VT and VF and is the leading cause of electrical death is sufficient to fix the answer without any doubt. But, the  truth is, the link between Ischemia and cardiac arrhythmia is more complex   If we could agree ischemia is a powerful trigger of ventricular arrhythmia, will every patient with chronic stable angina be at risk of  VT after walking a certain distance?   So, where does cardiac arrhythmia fall in the Ischemic cascade of events? the fact that chronic i...
