An electrocardiogram (ECG or EKG) is a non-invasive diagnostic test that records the electrical activity of the heart over a period of time. This test is commonly used to detect and diagnose heart conditions such as irregular heart rhythms, heart attacks, and cardiovascular disease. As the heart beats, electrodes are applied to the skin to measure electrical impulses.
An ECG is typically prepared by:
To allow easy access to the chest area where the electrodes will be placed, patients may be asked to remove clothing from the waist up and wear a gown during the procedure.
To ensure accurate readings, it is important to clean the areas where the electrodes will be placed.
The healthcare provider should be informed about any medications the patient is taking, since certain medications may affect the ECG results.
An ECG typically involves the following steps:
Small adhesive electrodes are placed on the chest, arms, and legs. These electrodes are connected to the ECG machine, which records the heart's electrical signals.
An ECG machine records the electrical activity of the heart as it beats, producing waves and complexes on graph paper or a computer screen.
Healthcare providers monitor ECG tracings in real time to ensure accurate recordings and identify abnormalities.
Upon completion of the ECG, the electrodes are removed, and the patient can resume normal activities.
ECGs usually do not require a recovery period, and patients can resume their normal activities immediately.
There are no risks or complications associated with ECGs, which are safe and noninvasive.
The following instructions may be given to patients after an ECG:
A healthcare provider may recommend further evaluation or treatment based on the results of the ECG and the patient's medical history.
Patients should report any symptoms that may indicate a heart problem to their healthcare provider, such as chest pain, shortness of breath, dizziness, or fainting.
An electrocardiogram (ECG or EKG) is a valuable diagnostic tool used to assess the electrical activity of the heart and detect various heart conditions. Healthcare providers can use this method to diagnose and manage heart-related problems because it is a safe and noninvasive procedure. Consult a healthcare provider if you have any concerns about your heart health or are experiencing symptoms of a heart problem.
