Electrocardiogram

What is an electrocardiogram (ECG)?

An electrocardiogram (ECG) is a non-invasive test that records the electrical activity of the heart. This test is essential for detecting and monitoring heart conditions such as arrhythmias, myocardial infarction and other heart rhythm problems. At CorePrime, we use state-of-the-art technology to ensure accurate and fast results.

The ECG is used to detect arrhythmias, including atrial fibrillation, atrial flutter, tachycardia and bradycardia such as atrioventricular block. These heart rhythm problems can cause symptoms such as palpitations, dizziness and fainting (syncope or lipoptysis).

In chest pain, an ECG can help determine the cause, such as a heart attack or other heart conditions. The test records changes in the heart's electrical activity that may indicate acute problems.

Patients with known heart conditions may benefit from regular ECG monitoring of heart function to assess the effectiveness of treatments and adjust medications as needed.

What is an electrocardiogram (ECG)?

Interpreting the electrocardiogram (EKG) is an essential process performed by CorePrime cardiologists. The resulting graph provides detailed information about your heart rhythm and heart rate, as well as any abnormalities. The doctor may recommend further investigations or treatments depending on the results.

The EKG chart is made up of several segments and waves that reflect different phases of the cardiac cycle:

The P wave reflects atrial depolarization and is an indicator of normal atrial function;
The QRS complex represents ventricular depolarization. Abnormalities in this segment may indicate problems such as bundle branch block or ventricular hypertrophy;
The T wave reflects ventricular repolarization. Changes in this wave may suggest ischemia or other heart conditions.

The doctor also pays attention to PR and QT intervals when interpreting the electrocardiogram. The PR interval measures the time it takes to conduct the electrical impulse from the atria to the ventricles. A prolonged PR interval may indicate atrioventricular block. The QT interval is associated with the time required for depolarization and repolarization of the ventricles. An abnormal QT interval may predispose the patient to severe arrhythmias and even cardiac arrest.

Interpreting EKG results also involves identifying and analyzing specific changes:

ST-segment elevation may indicate myocardial ischemia or subendocardial lesions;
ST-segment elevation is often associated with acute myocardial infarction;
Inverted T waves may suggest ischemia or electrolyte disturbances.

Based on the EKG interpretation, the cardiologist can confirm the diagnosis, plan treatment and recommend further investigations.

By utilizing advanced technology and medical expertise, CorePrime ensures accurate interpretation of electrocardiograms, contributing to effective management of patients' cardiac health.
