Many noninvasive and invasive tests can delineate cardiac structure and function (see table Tests for Assessing Cardiac Anatomy and Function Tests for Assessing Cardiac Anatomy and Function ). Also, treatments can be administered during certain invasive diagnostic tests (eg, percutaneous coronary intervention Percutaneous Coronary Interventions (PCI) Percutaneous coronary interventions (PCI) include percutaneous transluminal coronary angioplasty (PTCA) with or without stent insertion. Primary indications are treatment of Angina pectoris... read more during cardiac catheterization Cardiac Catheterization Cardiac catheterization is the passage of a catheter through peripheral arteries or veins into cardiac chambers, the pulmonary artery, and coronary arteries and veins.

Treatment is directed at causes. If necessary, direct antiarrhythmic therapy, including antiarrhythmic... read more during electrophysiologic testing Electrophysiologic Studies (EPS) In electrophysiologic studies (EPS), recording and stimulating electrodes are inserted into all 4 cardiac chambers via right- or left-sided cardiac catheterization. Atria are paced from the... read more ).
