Baseline ECG characteristics of some the persons with short QT interval. (A) [case #1] a 52 Y/O male with a score 3 QTc, bradycardia (HR: 49) and AF. PQ segment depression is noted; (B) [case #2] a 43 Y/O male with a score 3 QTc. A notch in aVL lead in favor of scarring and a biphasic T wave are noted; (C) [case #17] a 46 Y/O male with a score 1 QTc, bradycardia (HR: 50), low voltage ECG and syncope; (D) [case #59] a 53 Y/O male with a score 1 QTc, relative bradycardia (HR: 59), AF, and counter clockwise rotation who expired due to SCD during the cohort; (E) [case #64] a 54 Y/O male with a score 1 QTc and relative bradycardia who was suspicious to the type II Brugada syndrome (a saddleback ST segment elevation in lead V1 and a prominent R wave in lead aVR, but not fulfilled R wave sign). Brugada test was not performed.
