Figure 1From: Renal sympathetic denervation inhibites the development of left ventricular mechanical dyssynchrony during the progression of heart failure in dogs LV dyssynchrony in three directions (radial, circumferential and longitudinal) in the sham-operated group (sham), the pacing-induced heart failure group (control), and the group treated with renal sympathetic denervation and rapid ventricular pacing (RSD). LV mechanical dyssynchrony was assessed using the standard deviation of the time from onset of the QRS interval to peak strain.Back to article page
