Description

An electrocardiogram (ECG) test monitors heart rhythm and detects conditions like arrhythmia or ischemia; patients in China may need it for chest pain, palpitations, or preoperative assessment, with costs typically ranging from ¥200–¥500 and booking support available through ChinaMedicalHub.

Main Uses

The primary purposes of an ECG include diagnosing arrhythmias, detecting ischemia or infarction, evaluating the effects of drugs or electrolyte disturbances on the heart, assessing pacemaker function, and monitoring the progression of heart disease. It is also used in preoperative assessments and during physical examinations to establish a baseline cardiac health status.

Normal Range

A normal ECG (Electrocardiogram) typically shows a heart rate between 60-100 beats per minute, PR interval of 0.12-0.20 seconds, QRS duration of 0.06-0.10 seconds, and QT interval corrected for heart rate (QTc) less than 0.44 seconds. The P wave amplitude should be less than 0.25 mV in limb leads and less than 0.2 mV in precordial leads. The QRS complex amplitude should not exceed 2.5 mV in leads V5 and V6.

Low Values - Possible Causes

Bradycardia (heart rate below 60 bpm), hypothyroidism, electrolyte imbalances such as hyperkalemia, certain medications like beta-blockers or calcium channel blockers, and conditions affecting the sinoatrial node.

High Values - Possible Causes

Tachycardia (heart rate above 100 bpm), atrial fibrillation, ventricular tachycardia, stress or anxiety, fever, anemia, dehydration, and thyroid disorders such as hyperthyroidism.
