A 76 year-old woman with a history of coronary artery bypass grafting and prior myocardial infarction was transferred to theemergency room with loss of consciousness due to marked bradycardia caused by hyperkalemia. The concentration of serumpotassium was high, and normal sinus rhythm was restored after correction of the serum potassium level...

We present the case of a 25 year-old man referred for an electrophysiological study due to suspected pre-excitation as the cause of two recent syncopal episodes. The admission electrocardiogram (ECG) showed a borderline PR interval of 120 ms and apparently small delta waves visible in leads V2–V4...

Global cerebral hypoperfusion resulting in syncope, and asynchronous discharge of cerebral neurons leading to seizure, are two major mechanisms of transient loss of consciousness. They both have a lot in common in clinical and historical settings, although with a high prevalence of incorrect diagnosis, even by well-trained staff...

The Fontan procedure has become a generic term to define a surgical procedure that orients the systemic venous return directly to the pulmonary arteries, and has been used as a palliative operation for pulmonary atresia, tricuspid atresia, double inlet ventricle and complex single ventricle...

We present a case of a 31 year-old male patient with a congenital heart disease — bicuspid aortic valve with secondary aortic valve insufficiency, in whom recurrent syncope associated with episodes of complete atrioventricular block was observed. After implantation of a pacemaker syncope did not reccur...

This is a 12-lead electrocardiogram (ECG) of a 26 year-old male patient with myotonic dystrophy type 1 (DM1) diagnosed eight years previously, with severe distal muscular weakness, gait, speech and mastication disorders, and mild mental retardation. A positive family history with similar manifestations was present (mother and brother, the latter presenting with sudden death at the age of 34)...

Prolonged corrected QT interval (QTc) holds independent prognostic importance in predicting mortality in patients with coronary artery disease, diabetes mellitus and congestive heart failure. However, its association with all cause or cardiac mortality in the general population remains unclear. We evaluated the relationship between prolonged QTc and total mortality among patients with syncope...

This article presents a new approach to ambulatory arrhythmia monitoring, one which can be viewed as a natural evolution of the existing non-invasive methods for diagnosing heart rhythm abnormalities. This new method combines the real-time capabilities of modern mobile cardiovascular telemetry systems with a quantitative way of reporting measured findings and continuous storage of the ECG data typical of Holter monitoring systems...

Although pericardial cysts are generally benign structures and detected incidentally, they may be associated with life-threatening complications. We present the case of a 24 year-old man with a giant hemorrhagic pericardial cyst diagnosed after evaluation for recurrent syncope which caused compression of the right ventricle.
