Abstract：Electrocardiogram (ECG) and echocardiography are both routine examinations for heart diseases with unique advantages in the diagnosis and treatment of heart diseases. ECG focuses on the rhythm and frequency of heartbeats, and electrical conduction while echocardiography is good at displaying the structure and morphology of the heart such as the valve, the size of each chamber, the speed and direction of blood flow, and ventricular volume changes during the systolic and diastolic periods of the heart. In clinical practice, the two seek a common ground while they reserve differences, and complement each others advantages. This article briefly introduces the invention of ECG and echocardiography, focuses on their respective advantages in clinical application, and emphasizes the important role of their complementation in clinical practice.
