Emergency coronary angiography 2004 honda civic exhaust system revealed that a large filling defect remained due to an extensive thrombus in the proximal left circumflex (LCX) with thrombolysis in myocardial infarction (TIMI) grade 2 flow, and then a repeat thrombus aspiration was performed.After reperfusion, the parameters of the right ventricular lead were gradually returned.We conclude that the loss of the right ventricular lead pacing occurred in this case of acute coronary syndrome (ACS) induced by an stella mccartney denim jumpsuit LCX thrombus due to an LCX supplying the right ventricular septal.
