Background. Transient arrhythmias can affect transient ischemic dilation (TID) ratios. This study was initiated to evaluate the frequency and effect of normal heart rate change on TID measures in ...

Illustrative cases demonstrating how change in heart rate can affect transient ischemic dilation (TID) ratios. (a) Low-risk left ventricular perfusion pattern (equivocal in the posterobasal ...
