Kazuhiro Takahashi, MD, PhD, Taisuke Ishikawa, DVM, PhD, Naomasa Makita, MD, PhD, Kiyotaka Takefuta, MD, Taisuke Nabeshima, MD, Mami Nakayashiro, MD  HeartRhythm Case Reports  Volume 3, Issue 1, Pages (January 2017) DOI: /j.hrcr Copyright © 2016 Heart Rhythm Society Terms and Conditions

2 Figure 1 A: Initial 12-lead electrocardiogram shows bidirectional premature ventricular beats. B: QT prolongation during sinus bradycardia at night. C: Torsades de pointes with increasing heart rate. HeartRhythm Case Reports 2017 3, 69-72DOI: ( /j.hrcr ) Copyright © 2016 Heart Rhythm Society Terms and Conditions

3 Figure 2 A novel CALM1 mutation E105A. Upper panel indicates the sequence pherogram of the novel CALM1 missense mutation E105A. Lower panel shows schematic representations of the Ca2+ binding loops in the N-terminal (I and II) and C-terminal (III and IV) and the locations of mutations. Red circle represents the CALM1-E105A identified in our present study and green symbols represents CALM1 and CALM2 mutations previously reported.
