ECG at Home

A 12-lead ECG records the electrical activity of your heart from 12 different angles using 10 electrodes placed on your chest and limbs. It provides a comprehensive view of heart rhythm, rate, conduction, and any signs of ischemia or structural abnormality. It is the standard first-line cardiac diagnostic used worldwide and can detect conditions such as atrial fibrillation, heart block, myocardial ischaemia, and ventricular hypertrophy within seconds of recording.

The actual recording takes approximately 10 seconds once all electrodes are in place. Including preparation, electrode placement, quality verification, and a brief explanation of findings, the entire visit takes approximately 20 to 30 minutes. For Holter monitor setup, allow an additional 15 to 20 minutes for device fitting and diary log instructions.

Yes. We use the same calibrated, medical-grade 12-lead ECG machines used in hospital cardiac departments. The recording quality is identical when performed by a trained technician following standard electrode placement protocols. In fact, a home ECG can sometimes provide a more accurate baseline reading because the patient is relaxed in their own environment rather than anxious in a clinical setting, which can affect heart rate and rhythm.

A Holter monitor is a portable device that continuously records your heart rhythm for 24 to 48 hours while you go about your normal daily activities. It is used when a standard ECG does not capture intermittent symptoms such as occasional palpitations, brief dizzy spells, or suspected paroxysmal atrial fibrillation. Our technician fits the device at your home and returns to collect it at the end of the monitoring period. The full recording is then analysed by a cardiologist.

Every ECG recording is reviewed and interpreted by a qualified cardiologist, not by software alone. The cardiologist provides a written report including rhythm analysis, rate assessment, axis determination, interval measurements, and any abnormal findings with clinical recommendations. If an urgent abnormality is detected, the cardiologist contacts you or your referring physician immediately by phone.

Yes, an ECG can and should be performed on patients with pacemakers to verify appropriate device function and assess underlying rhythm. Our technicians are trained to identify pacemaker spikes on the tracing and the reporting cardiologist will assess capture and sensing function. However, a full pacemaker interrogation requires separate device-specific equipment and should be performed at a cardiology clinic.

No. You should take all your medications as prescribed. In fact, it is important that the ECG is recorded while you are on your usual medications, as one of the purposes may be to monitor how those medications affect your heart rhythm and intervals. Your medication list will be noted on the report so the interpreting cardiologist can account for expected drug effects.

If the cardiologist identifies an urgent finding, you will be contacted immediately by phone with guidance on next steps, which may include proceeding to a hospital emergency department or scheduling an urgent cardiology consultation. For non-urgent abnormalities, the report will include recommendations such as an echocardiogram, stress test, or cardiology review, which can be arranged at our DHCC clinic or with your own cardiologist.
