Myocardial perfusion imaging detects reduced blood flow and coronary artery disease with high accuracy. Advanced positron-emission imaging assesses blood flow and viability. Non-invasive CT imaging evaluates coronary anatomy and calcium scoring for cardiovascular risk.

Up to 30 days of continuous, real-time rhythm monitoring helps catch arrhythmias that standard EKGs miss. Long-term monitoring supports patients with unexplained fainting, palpitations, or suspected atrial fibrillation. Carotid, peripheral arterial, and venous studies evaluate circulation, stroke risk, and blood clots. Longitudinal care is coordinated with primary doctors to keep patients stable. Services include evaluation and management of irregular heart rhythms, blood pressure monitoring, lipid review, and dietary counseling.
