The growing prevalence of cardiovascular diseases, increasing demand for remote patient monitoring, and advancements in wearable healthcare technologies are accelerating the adoption of Holter ECG systems worldwide. Holter electrocardiography (ECG) devices play a critical role in continuously monitoring cardiac activity over 24 hours or longer, helping clinicians detect arrhythmias, irregular heart rhythms, and hidden cardiac abnormalities.
The global holter ECG market, valued at US$0.44 billion in 2024, stood at US$0.49 billion in 2025 and is projected to advance at a resilient CAGR of 6.5% from 2025 to 2030, culminating in a forecasted valuation of US$0.76 billion by the end of the period. A Holter ECG, also known as a continuous monitor, is a small and advanced ambulatory device that continuously records the heart’s electrical activity for 24 to 48 hours.
