Electrocardiogram, which is a non-invasive, painless test, is one of the bases to help doctors diagnose abnormal heart problems. In medicine, the use of electrocardiogram helps to detect cardiovascular diseases such as arrhythmia, heart failure, myocardial infarction, diagnose some changes, general heart disorders.

The atrium is the upper chamber of the heart, which is the place through which blood enters the ventricles. The human heart has two atria, the left atrium receives blood from the pulmonary circulation and the right atrium receives blood from the venous circulation. The atria perform three different functions during a cardiac cycle: as the receiving chamber during systole, passively pumping blood into the ventricles during early diastole, and intensively pumping during late diastole.

Hi doctor! During the day I have 4-5 times my heart convulsion (vibration), in 2-3 seconds then it goes away, feeling scared and then feeling tired. My blood pressure dropped to 10 degrees 3 years ago, after I was overworked. Right now my blood pressure is still 10 degrees. I went to Saigon to check, measure the ECG and the results of sinus bradycardia. Thanks to the doctor for treatment advice, thanks!

Cardiovascular diseases such as coronary artery disease, cerebral artery disease, peripheral artery disease, etc. are tending to be younger, accounting for 77% of annual deaths. For the prevention and early detection of cardiovascular diseases, electrocardiography is an indispensable method when screening for cardiovascular disease.

Electrocardiogram is considered an extremely necessary subclinical technique in detecting and diagnosing a number of diseases related to arrhythmias or structural abnormalities of the heart. In particular, the P wave is an important element in the leads of the electrocardiogram, which helps us to investigate a number of cardiovascular abnormalities.

Hi doctor. Doctor let me ask, how is coronary artery disease diagnosed? Looking forward to hearing from you soon. I sincerely thank.

Hello doctor. Recently I have pain in the middle of my chest. 10 days ago I had an echocardiogram, the electrocardiogram showed normal results. I have no signs of coughing, shortness of breath but only pain in the middle of the chest.

About a month ago, I often felt nervous like palpitations, sometimes I had to take a deep breath to ease my breath. I went for an echocardiogram and the results were normal, but the electrocardiogram showed excess ventricular extrasystoles. How to treat ventricular extrasystoles?

Hello doctor! I am 33 years old this year, sometimes I worry too much or get stressed, I have palpitations, tachycardia.

What is supraventricular tachycardia? This is a condition in which the heart suddenly beats abnormally fast. The condition is usually not dangerous, but patients need to be hospitalized for treatment if symptoms persist.

I have symptoms of dizziness, weak limbs when moving, shortness of breath when lying down, rapid pulse, difficulty sleeping. My blood pressure is normal. I have been like this for two days, taking pain relievers, it helps and I can sleep. So the doctor asked me what is the disease with weak hands and feet, shortness of breath with a fast pulse?
