ECG findings of acute myocardial infarction and atrioventricular block during a transseptal procedure for left atrial ablation. (43/265)

We report on a patient with transient atrioventricular block and ST-segment elevation mimicking the ECG of myocardial infarction during transseptal puncture for radiofrequency catheter ablation of atrial fibrillation. Symptoms and EGG findings resolved spontaneously. A neurally-mediated mechanism, activated by the mechanical effects of the transseptal puncture on the interatrial septum and leading to coronary artery spasm, may be considered as a possible explanation of this phenomenon. Coronary artery embolism following the transseptal procedure represents an alternative mechanism. The above mechanisms could also explain the atrioventricular block.  (+info)

Transient 2:1 atrioventricular block following anaphylactic reaction to low-ionic strength computed tomography contrast agent. (48/265)

The present report describes the case of an elderly woman who was admitted to the hospital with sepsis and subsequently developed a transient 2:1 atrioventricular block following administration of a low-ionic strength contrast agent for computed tomography. The block resolved after approximately 24 h and did not require a temporary pacemaker. The case identifies an unusual consequence following an anaphylactic reaction to a low-ionic strength computed tomography contrast agent and suggests the potential role of histamine release as a mechanism underlying this reaction.  (+info)
