A electrocardiogram at rest (ECG) is a painless test that records the electrical activity of your muscle. It involves placing small sensors on your chest, arms, and legs. These sensors transmit data to a machine that creates a graph of your heart's beat. An ECG at rest can help your doctor identify various cardiovascular diseases, such as irregular heartbeats. It is often performed as part of a physical examination.
Stress ECG Monitoring
An treadmill stress test electrocardiography (ECG) is a valuable tool used to assess the heart's function during higher physical exertion. During the test, patients run on a treadmill while their ECG is recorded. This allows cardiologists to identify any abnormalities in the heart's rhythm or function that may not be present at rest.
The test can help reveal a range of heart conditions, such as coronary artery disease, arrhythmias, and heart failure. By observing how the heart responds to stress, doctors can get a more comprehensive understanding of its overall health and functionality.
Extended Holter Electrocardiogram
A continuous Holter electrocardiogram monitoring, also known as a Holter monitor, is a portable device that records your heart's rhythm over an extended duration. Typically worn for 24 hours, the Holter monitor documents your heart rhythm throughout everyday activities. This allows physicians to identify any abnormalities that may not be evident during a standard electrocardiogram (ECG) test conducted in a clinical setting. The information gathered from the Holter monitor can be valuable for diagnosing a variety of heart conditions, including arrhythmias, electrical disturbances, and other cardiac issues.

If your physician suspects a heart rhythm problem, they may recommend a Holter monitor to provide in-depth information about your heart's activity over time.

Analysis of Cardiac Function During Exercise Testing (ECG)
During exercise testing, electrocardiography (ECG) plays a crucial role in evaluating cardiac function. As the individual exercises, their heart rate and rhythm elevate. The ECG provides real-time visualization of these changes, enabling clinicians to pinpoint any discrepancies in electrical activity.
These abnormalities may include ST-segment depression, T-wave alterations, and arrhythmias, which can suggest underlying vascular disease. By examining the ECG during exercise, clinicians can determine the functional capacity of the heart and uncover potential risks associated with physical activity.
Continuous ECG Monitoring for Symptom Evaluation
Ambulatory ECG monitoring is a valuable tool for assessing symptoms that may be related to cardiac activity. A portable ECG device, usually worn for 24 to 48 hours, records the ECG's electrical signals continuously. This prolonged monitoring allows healthcare professionals to detect infrequent abnormalities in heart rhythm that may not be observed during a standard, short-term ECG test in the clinic. The recorded data can then be reviewed by a cardiologist to offer valuable insights into the patient's {underlying{ conditions and guide treatment decisions.
Benefits of ambulatory ECG monitoring include its ability to:
- Document infrequent arrhythmias
- Evaluate the impact of daily activities on heart rhythm
- Present objective evidence for symptom-related complaints
- Inform treatment plans and medication changes
