After the ECG or 24-hour Holter monitor used up to now, the long-term Holter monitor is now available at the Wáberer Cardiology Centre, which will make it much easier to screen patients for heart problems in the future. Unlike the conventional device, the new monitor can be worn undetected for up to 7 days and can even be used for sports, but its biggest advantage is that it can effectively detect hidden, less frequent complaints. According to Dr. Márton Vértesaljai, specialist in internal medicine and cardiology at the Wáberer Cardiology Centre, the new device could play an important role in prevention and even more accurate diagnosis.
