Explanation

ECG (Electrocardiogram) records the electrical activity of the heart from electrodes placed on the skin. It shows the cardiac cycle (P wave, QRS complex, T wave) and is essential for diagnosing arrhythmias, myocardial infarction, conduction defects, and electrolyte imbalances. EEG (Electroencephalogram) is for brain electrical activity. Kidney function tests (creatinine, BUN) and liver function tests assess those organs. ECG is exclusively cardiac.
