Representative images of coronary angiography and fractional flow reserve (FFR) from a patient who showed no resting ECG abnormality. Representative images of coronary angiography and fractional flow reserve (FFR) from a patient who showed no resting ECG abnormality. The average Multifunction CardioGram value of this patient was 6.0, and two vessel disease in the proximal left anterior descending artery (FFR=0.70) in panel A, and the mid right coronary artery (FFR=0.72) in panel B were found. Arrows show the jump up points of FFR. Tetsuya Amano et al. Open Heart 2014;1:e000144 ©2014 by British Cardiovascular Society
