Holter Monitor adalah alat kecil seukur HP yang anda pakai 24-48 jam dengan elektrod ditampal pada dada. Ia rakam setiap denyutan jantung secara berterusan sambil anda lakukan aktiviti harian biasa — kerja, tidur, makan, exercise. Apabila aritmia berlaku, ia akan terakam dengan tepat masa, jenis, dan keterukan. Tanpa Holter, banyak aritmia paroxysmal (datang-pergi) langsung tak dapat didiagnosis.
Holter Monitor is a small device the size of a phone that you wear for 24-48 hours with electrodes on your chest. It records every heartbeat continuously while you do normal daily activities — work, sleep, eat, exercise. When arrhythmia occurs, it gets recorded with exact time, type, and severity. Without Holter, many paroxysmal arrhythmias (come-and-go) cannot be diagnosed at all.
Mengapa ECG Biasa Tak Cukup
Why Regular ECG Isn't Enough
ECG hospital biasanya 12-lead resting — ia rakam aktiviti elektrik jantung selama 10 saat sahaja. Bayangkan anda nak tangkap kucing yang muncul sekali sehari, dan anda buka mata 10 saat sehari — peluang berjaya hampir sifar. Begitulah ECG biasa dengan aritmia paroxysmal. Holter Monitor 24-jam memberi 8,640 kali lebih banyak data (864,000 saat berbanding 10 saat). Itulah sebab cardiologist akan order Holter selepas ECG normal jika simptom anda terus berlaku.
Hospital ECG is usually 12-lead resting — it records cardiac electrical activity for only 10 seconds. Imagine catching a cat that appears once a day, and you open your eyes 10 seconds per day — near-zero chance of success. That's regular ECG with paroxysmal arrhythmia. 24-hour Holter Monitor gives 8,640× more data (864,000 seconds vs 10 seconds). That's why cardiologists order Holter after a normal ECG if symptoms persist.
Holter 24 Jam vs 48 Jam — Bila Pilih Mana?
Holter 24h vs 48h — When to Pick Which?
Kos Holter di ANNUR bermula RM500 (24-jam) hingga RM1,000 (48-jam, termasuk laporan cardiologist). Berbaloi atau tidak bergantung kepada kekerapan simptom anda — bukan harga pun.
Holter cost at ANNUR starts at RM500 (24-hour) up to RM1,000 (48-hour, including cardiologist report). Worth it or not depends on your symptom frequency — not just price.

Selepas Holter — Apa Rawatan & Kos?
After Holter — What Treatment & Cost?
Holter sahaja diagnostik, bukan rawatan. Berdasarkan hasil, pakar akan cadang langkah seterusnya:
Holter alone is diagnostic, not therapeutic. Based on results, the specialist will recommend next steps:
Yang Kebanyakan Pesakit Salah Faham
What Most Patients Get Wrong
Pesakit selalu fikir: "Kalau Holter normal, maknanya tiada masalah." Salah. Holter normal hanya bermakna tiada aritmia dalam 24-48 jam tersebut. Kalau anda berdebar sekali sebulan, kebarangkalian Holter 24-jam menangkapnya adalah ~3%. Itulah sebab cardiologist mungkin cadang Event Monitor (rakam 1-4 minggu, RM800-1,500) atau Implantable Loop Recorder (rakam 2-3 tahun, RM8,000-15,000) untuk simptom yang sangat jarang tetapi membimbangkan.
Patients often think: "If Holter is normal, then nothing is wrong." Wrong. A normal Holter only means no arrhythmia in those 24-48 hours. If you have palpitations once a month, the chance of a 24-hour Holter catching it is ~3%. That's why cardiologists may recommend Event Monitor (records 1-4 weeks, RM800-1,500) or Implantable Loop Recorder (records 2-3 years, RM8,000-15,000) for very rare but concerning symptoms.
Dan ini penting: Holter Monitor bukan rawatan. Ia alat diagnostik. Pakar yang membaca Holter adalah Cardiologist, bukan GP. Pastikan pakej yang anda beli sudah include konsultasi dengan cardiologist sebenar — bukan sekadar GP yang baca laporan komputer. Di ANNUR, semua Holter dianalisa dan disahkan oleh Pakar Kardiologi.
And this matters: Holter Monitor is not treatment. It's a diagnostic tool. The specialist who reads Holter is a Cardiologist, not a GP. Make sure the package you buy includes consultation with an actual cardiologist — not just a GP reading a computer report. At ANNUR, every Holter is analyzed and signed off by a Cardiology Specialist.
