Bradycardia
Analysis in the EMERGEncy Between TransVenous Cardiac PACIng Guided by Fluoroscopy Versus Echocardiogram
A lot of questions about use of temporary transvenous pacing still remain obscure and there is no effective comparison between use of fluoroscopy versus electrocardiogram/echocardiogram in patients with bradicardias.

Giant T-wave Electrical Alternans
The Effect of Late Na Current Blocker Mexiletine on Giant T-wave Electrical Alternans(STOP-TWA)
The electrocardiogram is one of the most basic tests for cardiovascular disease. T wave alternans (TWA), which reflects abnormal ventricular repolarization, can easily trigger ventricular tachycardia (VT) and ventricular…
