Intra-procedural arrhythmia during cardiac catheterization: A systematic review of literature

Figure 1 Graphic view of reported incidence rates of ventricular tachycardia / ventricular fibrillation during coronary angiography. Gau et al[29] reported in 1970, an outlier with high incidence of ventricular fibrillation (VF) in their early experience of 75 cases of coronary angiography (CAG). Excluding the outlier, other reported VF/ventricular tachycardia (VT) incidence rates were consistently low with median 0.9%, (range 0.1% to 1.7%). Total reported CAG cases excluding the 75 cases in Gau et al[29] were 163015, and total VF/VT cases 1251, with the incidence rate of 0.8%. VF: Ventricular fibrillation; VT: Ventricular tachycardia.
