Abstract
We present an example of sudden modification in QRS morphology during ventricular pacing inside a scar-related isthmus. This is explained by a "concealed" sudden block in both the orthodromic and antidromic wavefront directions, allowing then the activation to proceed through a now overt antidromic conduction.
摘要
我们展示了一个在瘢痕相关峡部内进行心室起搏时QRS形态突然改变的例子。这是由顺向和逆向波前方向上的“隐匿性”突然阻滞所解释的，随后允许激动通过现在明显的逆向传导继续进行。
