What does it mean to have a question mark on the electrocardiogram?

The question mark on the electrocardiogram generally indicates that the instrument may be abnormal or the patient's body is abnormal. When operating ECG, if the electrode connection is poor or the patient's mood is unstable, it may lead to question marks on ECG. Therefore, when measuring ECG, we should pay attention to the operating specifications to ensure the accuracy of the measurement.

Electrocardiogram (ECG) is a common cardiac examination method, which can reflect the electrical activity and rhythm of the heart. When there is a question mark in ECG, we generally need to carry out further examination and judge the problem in combination with the patient's clinical manifestations. Common causes include irregular heartbeat and myocardial infarction, which need early detection and treatment.

The question mark of ECG is one of the important basis for the diagnosis of heart disease. For some patients, the question mark on ECG may be a physiological reaction or an early manifestation of the disease. Therefore, early diagnosis and treatment are very important for patients' health. At the same time, we should also pay attention to the operation of ECG and correct mind reading to avoid misdiagnosis and missed diagnosis and provide better medical services for patients.
