Intractable ventriculat tachycardia in ventricular aneurysm

If any one of the clinical symptoms are present in Left Ventricular Aneurysm, surgery is indicated.

1. Angina
2. CHF
3. Systemic thrombolism
4. Malignant Arrhythmias

Intractable ventriculat tachycardia in the postmyocardial infarction patient should alert the physician for the presence of ventricular aneurysm. Establishment of circus movement between the aneurysmal and viable myocardium play a role. Ischemic dead and fibrosed tissue may help in establishing reentry phenomenon by creating an area of relative refractoriness and decrimental conduction. It can also act as an independently firing ectopic pacemaker site.
