Non-Invasive Cardiology

Non-Invasive Cardiology

John Muir Health offers comprehensive, highly advanced, non-invasive cardiac diagnostic procedures that enable our doctors to quickly assess, diagnose, and treat heart problems.   

Many of our well-trained clinical staff members hold special certifications indicating ongoing training in complex procedures.

The following non-invasive procedures are available at both our Walnut Creek and Concord campuses:

Electrocardiogram

Uses an electrocardiographic (EKG) machine to evaluate the electrical activity generated by the heart at rest and with activity.

Echocardiography

Uses ultrasound, or high-frequency sound waves, to create graphic images of the heart's structures, pumping action, and direction of blood flow. Stress echocardiography and transesophageal echocardiography (TEE) are also available.

Nuclear stress testing

A method of producing images by detecting radiation from different parts of the body after the administration of a radioactive tracer material.

Coronary angiography

Uses 64-slice computed tomography (CT) scan to reveal the internal structures of the heart and the coronary arteries (Concord campus only).
