A case of spontaneous pneumothorax presenting with high-degree atrioventricular block.

abstract：BACKGROUND:In a minority of the patients presenting with ST-segment elevation (STE) myocardial infarction (MI), electrocardiogram (ECG) may show a balanced STE in both anterior and inferior lead groups and may cause diagnostic confusion about involved myocardial territory. In this study, we sought ECG clues which may f...
