to investigate the mechanisms of ventricular fibrillation ( vf ) during coronary angiography , we assessed ventricular automaticity , local qt intervals , local conduction characteristics , and the ability to induce arrhythmias with premature ventricular stimulation in 30 dogs after intracoronary injections of 4 to 6 cc of renografin 76 ( rg 76 ) .
