Diagnostic Procedures

Diagnostic catheterization involves threading a thin tube into the heart to measure pressure and blood flow. It helps diagnose conditions like coronary artery disease, heart valve disorders, and heart failure, providing valuable information before interventional or surgical treatment.

Holter monitors are a type of mobile cardiac telemetry, which are portable devices that record continuous heart activity over 24 hours to several days. They are useful in evaluating palpitations and syncope, which often indicate underlying cardiac arrhythmia. These wearable devices allow our heart specialists in Sarasota and Venice to detect irregular heartbeats that may not appear during a standard EKG.

An electrocardiogram measures the heart’s electrical impulses to detect rhythm disturbances, conduction delays, or previous heart damage. ECGs are frequently performed in patients presenting with chest pain or palpitations. This simple and quick test remains one of the most essential tools for evaluating overall cardiac function.

Tilt table testing assesses how blood pressure and heart rate respond to changes in body position. It is particularly useful for diagnosing neurocardiogenic syncope and postural orthostatic tachycardia syndrome (POTS) in patients who experience dizziness or fainting. The test helps determine if an abnormal reflex or heart rhythm is responsible for symptoms.

Genetic testing helps identify inherited cardiac disorders that increase the risk of arrhythmias or sudden cardiac arrest. It is especially recommended for patients or families with a history of hypertrophic cardiomyopathy or long QT syndrome. Early identification of genetic risks allows for proactive monitoring and timely preventive care.

A cardiac PET scan uses a safe radioactive tracer to assess blood flow and detect damaged or scarred heart tissue. This advanced cardiac imaging method provides exceptional accuracy in evaluating coronary artery disease  and cardiomyopathy, helping guide revascularization or medical therapy decisions.

Nuclear stress testing measures how well blood flows through the heart during exercise or with medication that simulates exertion. It is a valuable tool for identifying ischemic heart disease and coronary blockages that may not be visible at rest. This test provides a clear picture of how the heart performs under stress conditions.

Echocardiography uses high-frequency ultrasound waves to produce detailed images of the heart’s chambers and valves. It is noninvasive, safe, and crucial for evaluating heart failure and valvular heart disease. This echocardiogram test allows cardiologists to assess heart function and detect structural abnormalities with precision.
