Research output: Contribution to journalArticlepeer-review


An 18-year-old girl with severe valvar pulmonary stenosis was subjected to balloon valvoplasty. During each inflation of the balloon, we observed transient electrocardiographic disappearance of 'R' waves in the monitoring lead. The possible explanations for this observation include sudden severe right ventricular strain and ischemia.
