Abstract:BackgroundJ waves may be augmented by coronary angiography (CAG) or intracoronary drug administration but the underlying mechanism is unknown.PurposeThe effect of intracoronary normal saline (NS) on J waves were investigated.Patients and methodsAfter the standard CAG using iopamidol (IopamiroR Inj), NS was injected into the right coronary artery in 10 patients with and eight patients without J waves at the baseline. The 12‐lead ECG was monitored, stored on a computer and retrieved later for measurement of the … Show more
