What do ECG B and W mean?

Electrocardiograms B and W are black and white representations of electrocardiogram, which are usually used in medical field. B stands for black, representing QRS complex in ECG, which is an electrophysiological phenomenon and is used to reflect the pacing and conduction function of the heart. W is white, representing P wave and T wave in ECG, and it is also an electrophysiological phenomenon, which is used to reflect the contraction and relaxation of the heart.

In ECG, the display of B and W plays an important role in the diagnosis of heart disease. B stands for QRS complex. If there is abnormal reaction, it may mean that the patient has problems such as ventricular tachycardia, ventricular hypertrophy and ventricular wall motion defect. W stands for p wave and t wave. If abnormal waveforms are found, it may mean atrial fibrillation, ventricular hypertrophy, myocardial ischemia and other problems, which are all diseases that need timely diagnosis and treatment.

In the field of modern medicine, electrocardiogram is an important detection method, which plays an important role in medical research, clinical diagnosis and health management. As a standardized method of ECG image, the B and W representations of ECG not only make the image clearer, but also provide more accurate diagnosis information for doctors and better treatment effect for patients.
