T he electrocardiogram shown in Figure 1 was read by the computer as arm-lead reversal. Th e computer reading went on to say that no further analysis would be attempted. Th is clearly is a programming mistake because the precordial leads make the diagnosis. Although we would estimate that 95% of electrocardiograms with negative P, QRS, and T waves in lead I are due to armlead reversal, a small ...

BACKGROUND Premature ventricular contractions (PVCs) originating from aortic sinus cusps is not infrequent and can be eliminated effectively by radiofrequency ablation with rare complications. However, after a review of the medical literature, and to our knowledge, this is the first case of successful idiopathic aortic sinus cusps-PVC-ablation using a 3-dimensional (3D) mapping system in an adu...

Dextroposition is a rare cardiac malformation defined as rightward displacement with leftward apex, vs. dextrocardia, which base-axis orientation. We report the second known case of dextroposition accessory pathway, presenting preexcited atrial tachycardia. Abnormal anatomy complicates ECG localization and pathway ablation. N/A A 50-year-old woman was admitted respiratory distress due to EBV in...

Tetralogy of Fallot (TOF) is commonly identified cyanotic congenital cardiac anomaly; however, its affiliation with dextrocardia and situs inversus very rare. We describe a case associated TOF in 23-year old girl who arrived central shunt at the age 17 years later for total surgical correction magnificent outcomes.

Dextrocardia with situs inversus occurs in approximately one in 10,000 individuals of whom 20% have primary ciliary dyskinesia inherited as an autosomal recessive trait. These patients have a high incidence of congenital cardiac disease but their risk of coronary artery disease is similar to that of the general population. We report what is, to our knowledge, the first case of total triple-vess...
