Excerpt

In this issue, Massalha et al retrospectively analyzed the conduction abnormalities that occurred with dipyridamole infusion.1 The authors examined 2010 patients, noting that 17.4% of the patients had baseline conduction abnormalities (defined as one fascicular block, bi-fascicular block, tri-fascicular block, non-specific intraventricular conduction delay (IVCD), atrial flutter or atrial fibrillation). After infusion of dipyridamole, it was noted that 16 patients had transient atrioventricular (AV) conduction changes; this was more pronounced in patients who already had baseline conduction abnormalities (0.3% vs 3.1%, P < .0001). While the low incidence of significant conduction abnormalities is reassuring, it is important to recognize the breadth of agents being used in vasodilator stress testing. …
