Does alpha thalassemia cause pvcs?

Probably not: Alpha thalassemia probably doesn't cause pvc's (premature ventricular beats, a type of extra heartbeat). However, some thalassemia patients have magnesium deficiency, which can make pvc's more likely to occur. Patients who get transfusions off and on may be drinking lots of coffee, using caffeine or phenols in coffee to decrease iron absorption, to hold off iron overload. Caffeine can cause pvc's.

No.: These two conditions are not related.
