摘要:
Right ventricular (RV) pacing related heart failure is reported in some patients after long term pacing. The exact mechanism is not yet clear but may be related to left ventricular (LV) dyssynchrony induced by RV apical pacing. We report one case with baseline normal LV ejection fraction but complicated by heart failure and ventricular tachycardia after 4 months of pacing for complete heart block together with illustration of LV dyssynchrony demonstrated by tissue Doppler imaging.
