Case ReportsReel syndrome and pulsatile liver in a patient with a two-chamber pacemaker.
Twiddler's syndrome is characterized by coiling of the pacemaker lead due to the rotation of the pacemaker generator on its long axis. Reel syndrome is another form of Twiddler's syndrome. ⋯ In this article we describe a patient with a two-chamber pacemaker who presented with sudden onset of abdominal pulsation and was subsequently diagnosed as Reel syndrome. To the best of our knowledge, this case is the first case of Reel syndrome that developed in a patient with a two-chamber pacemaker.

Use of recombinant activated factor VII in cardiac surgery for an effective treatment of severe intractable bleeding.
Experience gained with administration of supranormal-therapeutic doses (90 microg/kg) of recombinant activated factor VII in 7 cardiac surgery patients is presented. The patients were given recombinant activated factor VII postoperatively for intractable bleeding, 5 of them after surgical revision. ⋯ None of the patients needed reoperation. Administration of recombinant activated factor VII proved highly effective in management of massive hemorrhage in cardiac surgery.

Randomized Controlled Trial Clinical TrialExternal cardioversion in patients with persistent atrial fibrillation: a reappraisal of the effects of electrode pad position and transthoracic impedance on cardioversion success.
The optimal methods to perform external cardioversion of atrial fibrillation (AF) have yet to be conclusively determined. This study was performed to examine the relative efficacy of different pad positions on cardioversion success and the relationship between the transthoracic impedance (TTI) and energy requirement for AF cardioversion. Seventy patients with persistent AF undergoing elective cardioversion were randomly assigned to an electrode pad position situated either over the ventricular apex-right infraclavicular area (AL group, n = 31 ) or over the right lower sternal border-left infrascapular area close to the spine (AP group, n = 39). ⋯ Rather than pad position. TTI is the single factor that significantly affects cardioversion and correlates with energy requirement. The relationship between energy requirement and TTI further allows estimation of energy requirements to achieve a successfil cardioversion.

Case ReportsVerapamil sensitive idiopathic ventricular tachycardia in an infant.
Idiopathic ventricular tachycardia is rare, especially in infants. We report here on an 8 month-old female infant who presented with tachycardia with a heart rate of 186 beats/ min. ⋯ The tachycardia was terminated and well controlled with the use of verapamil. According to an electrocardiogram and her clinical response, verapamil-sensitive idiopathic ventricular tachycardia was diagnosed with the arrhythmic origin in the left posterior fascicle.

Pericardial effusion is frequently found in patients diagnosed with hypothyroidism, yet it is rarely associated with cardiac tamponade. This report presents an atypical case concerning a 60-year-old Taiwanese female, with a history of thyroidectomy surgery due to thyroid cancer, who was later diagnosed with myxedema and cardiac tamponade. Treatment included an immediate pericardiocentesis followed by thyroxine hormone replacement therapy. Postoperative and recovery phases progressed favorably, and the patient's prognosis is good.
