An electrocardiogram (ECG or EKG) is a widely used medical test that provides valuable insights into the electrical activity of the heart. The heart's electrical signals, responsible for regulating its rhythm, are generated by a cluster of cells known as the sinoatrial node (SA node) in the right atrium. These electrical impulses travel through the heart's muscle tissue, coordinating the contractions of the atria and ventricles. Remarkably, these electrical pathways can be detected on the...

An electrocardiogram (ECG or EKG) is a widely used medical test that provides valuable insights into the electrical activity of the heart. The heart's electrical signals, responsible for regulating its rhythm, are generated by a cluster of cells known as the sinoatrial node (SA node) in the right atrium. These electrical impulses travel through the heart's muscle tissue, coordinating the contractions of the atria and ventricles. Remarkably, these electrical pathways can be detected on the skin's surface. The ECG records these variations in electrical signals by measuring changes in voltage across different skin areas and represents them graphically as a waveform. This resulting graph, the electrocardiogram, offers essential information about cardiac activity, helping diagnose and monitor heart conditions.
When selecting an ECG machine for your practice, you need to consider several...
