Figure 8: CM-Specific SMAD4 Deletion Causes Cardiac Conduction Abnormalities

Electrocardiography (EKG) analysis was performed on mice at 4 weeks after TAM treatment and the following ECG parameters were examined: (A) heart rate (*p = 0.0426), (B) QRS interval (*p = 0.0127), (C) QT interval (***p = 0.0007), (D) QTc interval (**p = 0.0027), and (E) representative ECG traces. All p values are versus the CTL group. BPM = beats per minute; other abbreviations as in Figure 1.
