Treatment of Palpitations
Precipitating Some Drug Causes of Syncope are stopped. If dangerous or debilitating arrhythmias are caused by a necessary therapeutic drug, a different drug should be tried. For isolated PACs and PVCs in patients without structural heart disease, simple reassurance is appropriate. For otherwise healthy patients in whom these phenomena are disabling, a beta-blocker can be given provided efforts are made to avoid reinforcing the perception by anxious patients that they have a serious disorder. Identified rhythm disturbances and underlying disorders are investigated and treated (see table Some Treatments for Arrhythmias ). However, for rapid tachyarrhythmias in a patient in hemodynamic distress, cardioversion should precede further diagnostic assessment.
