• Cardiac electrophysiology: This is the study and testing of electrical currents that result in heartbeats. Your cardiologist can let you know if this testing is ideal for your case.
• CT scans: CT scans generate images that can be used in determining whether you have heart disease or atherosclerosis, otherwise known as plaque buildup on your arteries.
• Echocardiography: This involves using ultrasound waves to generate images of the heart and nearby structures, which enables cardiologists to observe your heart’s capacity for pumping blood, fighting off infections, and more. Plus, echocardiography can reveal structural abnormalities that could have a big impact on your cardiac health.
• Heart monitors: Wearing a heart monitor is another way for your cardiologist to monitor your heart’s activity and capacity. These monitors, also referred to as Holter monitors or cardiac event records, are a tape recorder of sorts for your heart’s electrical activity over a particular length of time.
• Nuclear cardiology: Through the use of radioactive element in imaging, nuclear cardiology is a noninvasive study of cardiovascular disorders. Careful imaging techniques can allow cardiologists to view different aspects of the heart and identify where problems may lie.
• Stress tests: Stress testing typically involves exercise and physical activity, which is closely observed by your cardiologist. By getting your blood pumping and your body moving, your heart will be performing under physical stress, and this activity can give your cardiologist valuable information about how your heart holds up in these situations.

Using these noninvasive procedures, your cardiac specialist may identify potential risks or existing conditions and recommend medications or lifestyle changes that will help improve your heart health.
