Does transvenous intracardiac pacing suppress recurrent ventricular tachyarrhythmia in patients after acute myocardial infarction who failed drug treatment?
Does transvenous intracardiac pacing suppress recurrent ventricular tachyarrhythmia in patients after acute myocardial infarction who failed drug treatment?
Transvenous intracardiac pacing can effectively suppress recurrent ventricular tachyarrhythmias refractory to drug treatment after acute myocardial infarction, potentially avoiding the need for repeated DC shocks.
May suppress refractory post-MI ventricular ectopy in select cases; hypothesis-generating and requires prospective trials before any practice change.
Transvenous intracardiac pacing was carried out on nine patients with recurrent ventricular tachyarrhythmia after drug treatment had failed. In eight patients recurrent Ventricular ectopic activity was suppressed by pacing at a rate above the sinus rate. With this technique the need for D.C. shock and repeated antiarrhythmic drugs can be avoided.
