What Is A Holter Test?
A Holter test is a portable, continuous ECG (electrocardiogram) recording that captures your heart’s electrical activity over an extended period — from 24 hours up to 7 days, depending on what your doctor recommends. You wear a compact, battery-operated device attached to a few small electrodes on your chest and simply go about your normal day.
Unlike a standard ECG, which lasts only a few minutes at the clinic, a Holter monitor records every heartbeat continuously over days. This makes it possible to capture irregular rhythms that only occur occasionally — during exercise, stress, sleep, or at unpredictable moments a short in-clinic test would miss.

Starting from ₹2,500 (price based on duration)
Prescription Required (doctor’s referral)
Diagnostic disclaimer: This test is a diagnostic aid. Results are reviewed and interpreted by a qualified RxDx cardiologist. A Holter recording does not constitute a standalone diagnosis. Your doctor will discuss findings and recommend next steps.
Why Would a Doctor Refer You for a Holter Test?
A Holter test is recommended when you have symptoms that come and go — and a standard ECG hasn’t captured them. The duration of monitoring is decided by your doctor based on how frequently your symptoms occur and what needs to be investigated.
| Your symptom or concern | What the Holter test looks for |
|---|---|
| Heart palpitations, fluttering, or skipped beats | Ectopic beats (PACs / PVCs), irregular rhythm patterns |
| Unexplained dizziness or lightheadedness | Arrhythmias causing momentary reduction in blood flow |
| Fainting spells (syncope) or near-blackouts | Bradycardia, pauses, or conduction blocks during the episode |
| Chest pain not captured on a standard ECG | Myocardial ischaemia — reduced blood flow to the heart muscle |
| Irregular heartbeat (known or suspected) | Atrial fibrillation, tachycardia, or bradycardia |
| Pacemaker check-up or medication review | Pacemaker function, response to heart rhythm medication |
Conditions a Holter test can help identify
- Atrial Fibrillation (AFib) — an irregular, chaotic heartbeat that increases stroke risk
- Tachycardia — episodes of abnormally fast heartbeat
- Bradycardia — unusually slow heart rate causing fatigue or fainting
- Premature beats (PACs / PVCs) — extra or skipped beats
- Myocardial Ischaemia — reduced blood flow to the heart muscle
How The Holter Test Is Done
Step-by-Step: What to Expect
Step 1 — Preparing for the test
- Shower before your appointment — you will not be able to bathe while wearing the device
- Do not apply lotions, oils, or creams on your chest on the day of the test
- Wear a loose, comfortable two-piece outfit — a button-down shirt is ideal
- Men may need a small area of chest hair shaved for the electrodes to stay in place
- Bring your doctor’s prescription and any previous ECG or cardiac reports
Step 2 — Device fitting (at the clinic, or at your home for home service)
A trained RxDx cardiac technician will clean the electrode sites on your chest, attach small adhesive electrode patches, and connect them to a compact, battery-operated Holter recorder. The technician will check signal quality and give you a symptom diary to use during the recording period.
Step 3 — During the recording
What you can do:
- Go to work, take gentle walks, cook, watch TV, sleep normally
- Press the ‘Event’ button on the device when you feel a symptom — palpitation, dizziness, or chest discomfort
- Note the time and activity in your symptom diary — critical for accurate analysis
What to avoid:
- Getting the device or electrodes wet — no baths, showers, or swimming
- Heavy exercise or contact sports unless specifically instructed by your doctor
- Strong electrical or magnetic fields — MRI machines, metal detectors, electric blankets
- Electric razors or toothbrushes used close to the device
Step 4 — Returning the device
At the end of the recording period, return the device to the RxDx clinic where it was fitted — or, if you have the home service, an RxDx technician will visit your home to collect it. Electrodes are removed quickly and painlessly, and the full recording is downloaded for analysis.
Step 5 — Your report (ready in 3 working days)
Your recording goes through a five-stage review process:
- AI rhythm analysis — automated algorithms scan every recorded heartbeat and identify rhythm patterns across the full recording
- Cardiac technician review — a trained RxDx cardiac technician goes through the entire recording, validates the AI findings, and manually annotates any additional rhythms or events
- Combined analysis — the AI’s rhythm interpretation and the technician’s manually analysed data are compiled together into a complete picture of your heart’s activity during the recording period
- Cardiologist review — the combined analysis is reviewed by an experienced RxDx cardiologist, who interprets all findings in the context of your symptoms and medical history
- Report sign-off — the cardiologist signs off the final report, which is then prepared and sent to you
Your report is available as a soft copy sent to your registered email, as a hard copy collected at the clinic — or both. Most patients choose both.

What Does Your Holter Report Show?
A Complete Picture of Your Heart Over Time
Your RxDx Holter report is not just a number or a single result — it is a detailed, multi-page clinical document prepared by our cardiology team. Here is what each section of the report tells you and your doctor.
| Report Section | What it contains | What it means for you |
|---|---|---|
| Summary Findings | Total heartbeats recorded, ventricular ectopic count and percentage, supraventricular ectopic count, fusion beats, signal quality | Gives your doctor the overall scale of the recording and how much of the heart’s activity was abnormal versus normal |
| Heart Rate Summary | Minimum heart rate (with exact time it occurred), maximum heart rate, average heart rate over the full recording period | Reveals how high or low your heart rate went, and exactly when — for example, whether a fast rate happened during sleep, exertion, or at rest |
| Ventricular Events | Counts of bigeminy (every other beat is abnormal), trigeminy, IVR/AIVR (slow abnormal rhythms), and VT/Poly VT (fast dangerous rhythms) | Identifies whether extra beats from the lower chambers are occasional or forming repetitive patterns, and whether any episodes of fast ventricular rhythm occurred |
| Supraventricular Events | Atrial bigeminy, Atrial Fibrillation (AFib), Atrial Tachycardia (AT), pauses longer than 2 seconds | Detects rhythm disturbances originating in the upper chambers of the heart, including AFib episodes and significant pauses that may explain dizziness or fainting |
| QT Interval Measurements | Maximum QT interval, maximum corrected QTc interval, and the times at which these occurred | A prolonged QT interval can indicate risk of serious arrhythmia. This is particularly important for patients on certain medications or with a family history of sudden cardiac events |
| Tachycardia Burden | Total number of tachycardia episodes and the percentage of total recording time spent in tachycardia | Helps your doctor understand how much of your day your heart was beating abnormally fast, and whether this is improving or worsening compared to previous tests |
| Arrhythmia Trend Timeline | A visual timeline across the full recording period marking critical events, major events, minor events, patient-triggered alerts, and day/night periods | Shows your doctor at a glance when abnormal events clustered — whether they were daytime, nocturnal, or triggered by specific activities you noted in your diary |
| R-R Analysis | R-R interval histogram (distribution of gaps between heartbeats) and R-R variation chart (how much the gaps vary beat to beat) | Reveals the regularity of your heart rhythm. A very narrow, consistent distribution suggests a regular rhythm; a wide, scattered distribution points to variability or irregular beats |
| Heart Rate — Sleep vs Awake | Separate heart rate statistics (minimum, maximum, average) broken down for sleeping and waking hours, with exact time windows | Isolates nocturnal arrhythmias, sleep-related bradycardia, or rates that don’t drop adequately during sleep — all of which have distinct clinical implications |
| Periodic Count Analysis | Hour-by-hour breakdown of heart rate and event counts across the full recording — ventricular events, supraventricular events, and nodal events listed per time block | Allows correlation between your symptom diary entries and the exact time blocks where the most events occurred — making diagnosis far more precise |
| Selected ECG Snapshots | Actual ECG tracings selected from the recording at clinically significant moments — including the fastest heart rate, slowest heart rate, and flagged arrhythmia episodes | Gives your cardiologist the actual electrical evidence behind every finding — not just a count, but a real look at what the heart was doing at that moment |
| Cardiologist’s Conclusion | A plain-language clinical summary written by the RxDx cardiologist, interpreting all findings in the context of your symptoms and medical history | This is the section your treating doctor will act on. It summarises the rhythm, any abnormalities found, their significance, and any recommended next steps |
A note on reading your report
Your Holter report contains a large amount of technical data — hundreds of thousands of heartbeats analysed across multiple dimensions. It is prepared specifically for your treating cardiologist, who will interpret the findings in the context of your symptoms, history, and medication. The Conclusion section is the most directly relevant part for you as a patient. Please do not attempt to self-diagnose from the technical pages — always review the full report with your doctor.

Frequently Asked Questions (FAQs)
What is a Holter monitor and why would I need one?
A Holter monitor is a portable ECG device that records every heartbeat continuously for a period determined by your doctor — from 24 hours up to 7 days. It helps detect arrhythmias that a short in-clinic ECG might miss. Doctors recommend it for palpitations, dizziness, fainting, chest pain not captured on a standard ECG, or to evaluate pacemaker function.
How long does the Holter test last?
How do I prepare for a Holter test?
What should I avoid while wearing a Holter monitor?
What should I do during the test?
Continue your normal daily routine. Keep a diary — log the time, activity, and any symptoms you notice. If you feel a palpitation, dizziness, or chest discomfort, press the Event button on the device and note it in your diary immediately. This helps your cardiologist match your symptoms to the exact point in the recording.
