2 例心脏手术后出现大量后部心包积液的患者，心电图出现心前区 Q 波，但没有心肌梗死的证据。心包液的消散导致 Q 波消失。心包腔内心脏电导率和方向的变化，以及 QRS 电压的降低，可能导致心前导联中初始 R 波的丢失，最终导致 QS 复合波。对于大量后部心包积液的患者，在心脏手术后解读心电图时应小心。临床病程以及连续心电图和超声心动图描记应有助于识别这种假性梗塞模式。
Two patients with a large posterior pericardial effusion after cardiac surgery presented with electrocardiographic precordial Q waves without evidence of myocardial infarction. Resolution of the pericardial fluid resulted in the disappearance of the Q waves. Changes in conductivity and orientation of the heart within the pericardial space, along wjth a decrease in QRS voltage, could lead to the loss of initial R waves in the precordial leads, eventually resulting in a QS complex. Care should be taken in interpreting the electrocardiogram after cardiac surgery in patients with a large posterior pericardial effusion. The clinical course along with serial electrocardiographic and echocardiographic tracings should be helpful in identifying this false infarction pattern.
