Some important Non-Invasive Cardiology Procedures are listed below for a general understanding.
  • 1.X-Rays – This specific Non-Invasive Cardiac heart test involves capturing images of the Heart using X-Rays. This is especially beneficial in identifying heart ailments related to the lungs. This is done by checking whether there is any fluid deposit happening in the lungs due to any problem in the heart.
  • 2.Stress Tests – These tests are conducted to check the functioning of the heart during physical stress and whether the patient is getting abnormally tired during the test. This helps in early identification of any heart related problems and whether the same can be improved by lifestyle related changes.
  • 3. Electrocardiogram (ECG or EKG) – One of the most popular non-invasive cardiology procedure, this method essentially checks the electrical pulses or heart beats. Non-invasive cardiology is carried out by connecting monitoring device to the skin of your chest and other pulse points and then monitoring the signals. The ECG is generally the first test advised by any cardiologist.
  • 4.Echocardiogram – While the ECG monitors the heartbeats by using electrical pulses, the echocardiogram (popularly called echo) utilizes high frequency sound waves to monitor the structure as well as functioning of the heart. This is also a common non-invasive heart test.
  • 5.Heart Monitors / Holter Monitors – These monitors are more like tape recorders used to record the activity of the heart over a certain period of time. This is then checked by the doctor to identify any problems.
  • 6.Cardiac Computed Tomography (CAT Scan) – The 3D imaging using computer-aided techniques encompasses a group of several non-invasive heart tests identifying blockages.
