Figure 5 The Distribution of Mechanical Asynchrony in DHF and SHF Subdivided by QRS Duration
Bar chart showing the distribution of patients who developed (A) diastolic and (B) systolic asynchrony in patients with DHF and SHF according to the QRS duration of  120 and >120 ms. As wide QRS is uncommon in DHF, the majority of patients with diastolic and systolic asynchrony occurred in the narrow QRS group. Abbreviations as in Figure 2.
