Clinic Procedures

Electrocardiography (ECG or EKG) is a process that measures the electrical activity of the heart through sensors called electrodes. Here’s an overview of how it works:

1. Electrode Placement: Several electrodes are placed on the skin, usually on the chest, arms, and legs. These electrodes detect electrical signals generated by the heart during its beating cycle.

2. Signal Detection: The heart produces electrical impulses during each heartbeat. These impulses travel through the electrodes to the ECG machine. Each electrode detects changes in electrical potential from different angles.

3. Data Transmission: The collected signals are transmitted to the ECG machine, where they are processed and displayed as a waveform.

4. Waveform Analysis: The ECG waveform consists of different parts (P wave, QRS complex, T wave) that represent various phases of the cardiac cycle, such as atrial depolarization, ventricular depolarization, and repolarization.

5. Interpretation: The recorded waveforms are analyzed by a physician to detect abnormalities like arrhythmias, ischemia, or heart damage.

ECG is non-invasive, quick, and a critical tool for diagnosing heart conditions. It can identify problems like heart attacks, irregular rhythms, and other heart-related issues, guiding effective treatment.
