How ECG Works
ECG works by attaching small electrodes to the skin at specific locations on the chest, arms, and legs. These electrodes detect the electrical signals generated by the heart as it beats. The signals are then transmitted to a machine that records the heart’s electrical activity, producing a graph or waveform. The pattern and timing of the electrical impulses on the ECG strip can help doctors diagnose any irregularities in heart function.
Common Uses of ECG
ECG is commonly used to diagnose a wide range of heart-related conditions, including:
- Arrhythmias: Detecting abnormal heart rhythms like atrial fibrillation, ventricular tachycardia, or bradycardia.
- Heart Attack: Identifying signs of a past or current heart attack by assessing changes in the heart’s electrical activity.
- Heart Disease: Assessing the heart’s electrical function in patients with known cardiovascular diseases or those at risk.
- Electrolyte Imbalances: Detecting irregularities that could suggest imbalances in blood potassium or calcium levels, affecting heart function.
- Preoperative Assessments: ECG is often used before surgery to evaluate the heart’s health and identify potential risks during procedures.
Benefits of ECG
ECG is a quick, painless, and effective way to monitor heart health. It helps detect potentially life-threatening heart conditions early, allowing for timely interventions. The test provides vital information regarding the heart’s electrical activity and can be performed in a variety of settings, including hospitals, clinics, and even during routine check-ups.
Safety
ECG is a safe and non-invasive procedure with no known risks. It is widely used in clinical settings and provides essential insights into heart health without the need for any invasive procedures.
