dysrhythmia must be very exact. With current methods, this limits application of the technique to cases where a stable unifocal ventricular tachycardia with a rate less than 200 beats/min is present in the operating room. It appears likely however that in the near future with the use of multiple simultaneously recorded electrodes and on-line computer analysis, more complex ventricular dysrhythm...

Background Cardiac MRI (CMR) is increasingly being used clinically to assess patients with ventricular dysrhythmias. Structural heart disease such as non-compaction is associated with dysrhythmic risk. Recent literature has characterized the regional thickness of the compacted and trabeculated layers of the left ventricle (LV) in normal subjects but not in patients with ventricular dysrhythmias...

Hyperkalemia is a commonly encountered electrolyte abnormality that can significantly alter normal cardiac conduction. Potentially lethal dysrhythmias associated with hyperkalemia include complete heart block and Mobitz Type II second-degree AV block. We report a case of trifascicular block, due to hyperkalemia. The patient's symptoms and electrocardiogram (ECG) evidence of trifascicular block ...

In clinical practice, stress testing might be performed due to lack of typical ST segment elevation in Wellens’ syndrome to obtain more evidence of cardiac ischemia. However, increasing cardiac demand during stress testing may result in acute myocardial infraction, and even fatal dysrhythmia and death [5]. Therefore, it is essential to consider the coronary angiogram as the initial diagnostic m...

BACKGROUND In 2006, the Israeli Ministry of Health distributed guidelines for improving cardiopulmonary resuscitation (CPR) knowledge among hospital staff. The impact of these guidelines on survival after in-hospital cardiac arrest (IHCA) is unclear. OBJECTIVES To compare rates of incidence and survival to discharge after IHCA, preceding and subsequent to issuance of the guidelines: 1995-2005...
