Description
A Holter monitor is a portable device used for continuous 24-hour heart rhythm recording to diagnose arrhythmias, unexplained dizziness, or palpitations; in China, typical costs range ¥200–¥500, and ChinaMedicalHub assists with hospital booking and interpreter support.
Main Uses
The primary purpose of a Holter monitor is to detect and diagnose irregular heartbeats, evaluate the effectiveness of heart medications, and assess the risk of future heart-related events. It is particularly useful in patients who experience symptoms such as palpitations, dizziness, or fainting, which may be related to heart rhythm disturbances but are not captured during a standard ECG.
Normal Range
A normal Holter monitor (动态心电图) reading typically shows a heart rate range of 60-100 beats per minute at rest, with variations depending on activity level. The ECG should not show any significant arrhythmias, ischemic changes, or conduction abnormalities.
Low Values - Possible Causes
Bradycardia (heart rate below 60 bpm), hypothyroidism, medication side effects (e.g., beta-blockers, calcium channel blockers), high levels of physical fitness, and electrolyte imbalances (such as hyperkalemia).
High Values - Possible Causes
Tachycardia (heart rate above 100 bpm), anxiety, stress, fever, anemia, dehydration, hyperthyroidism, and the use of stimulants (like caffeine or nicotine).
