What is the difference between an echocardiogram and an electrocardiogram

Time : 2022-12-30

Electrocardiogram can be referred to as ECG or EKG for short, which refers to the detection method of the electrical activity change pattern generated by each cardiac cycle of the heart recorded from the patient's body surface by an electrocardiogram machine.

What is the electrocardiogram?

An electrocardiogram is one of the important tests used to understand the state of the heart. An electrocardiogram is an examination that uses an electrocardiogram machine to record the beating of the patient's heart every cardiac cycle from the surface of the heart. Patients can play mobile phones, watch computers, go shopping and other daily activities during Holter ECG, but violent behaviors should be avoided. Patients do not need fasting for ECG, and there is no requirement for diet.

What is the difference between an echocardiogram and an electrocardiogram?

The difference between an echocardiogram and an ordinary electrocardiogram is that an echocardiogram mainly examines the patient's heart structure and blood flow, while an ordinary electrocardiogram mainly examines the patient's heart function, such as whether there is arrhythmia, myocardial infarction, myocardial ischemia, etc. Women can have an electrocardiogram when they are trying to conceive, and pregnant women need to have an electrocardiogram for prenatal checkups.

What are the advantages of a 12-lead ECG?

The advantage of twelve-lead ECG is that compared with three-lead and six-lead ECG, doctors can observe the waveform of ECG from more angles according to twelve-lead ECG. The 18-lead electrocardiogram can check whether the patient has myocardial infarction in the posterior visceral wall and right ventricle. In addition, the general examination is a 12-lead electrocardiogram.

The electrocardiogram is mainly to record the beat points, atrial and ventricular excitations of the human heart in each cardiac cycle, and the changes in the bioelectricity of the electrocardiogram. The method is to show the objective indicators of the process of cardiac excitation, such as occurrence, propagation, and recovery, and it plays a very important role in the diagnosis of various diseases such as ventricular and atrial hypertrophy.
