Masks are required inside all of our care facilities, COVID-19 testing locations on Maryland.gov, Diagnosis and Screening for Cardiovascular Conditions, Ciccarone Center for the Prevention of Heart Disease, To evaluate problems which may be heart-related, such as severe tiredness, shortness of breath, dizziness, or fainting, To help determine the overall health of the heart before procedures such as surgery; or after treatment for conditions such as a heart attack (myocardial infarction, or MI), endocarditis (inflammation or infection of one or more of the heart valves); or after heart surgery or cardiac catheterization, To see how an implanted pacemaker is working, To determine how well certain heart medicines are working, To get a baseline tracing of the heart's function during a physical exam; this may be used as a comparison with future ECGs, to determine if there have been any changes, Anatomical considerations, such as the size of the chest and the location of the heart within the chest, Electrolyte imbalances, such as too much or too little potassium, magnesium, or calcium in the blood.
