# Best Home EKG for Tracking AFib and Palpitations

> How to choose a home EKG monitor for documenting atrial fibrillation and heart palpitations, what the device can and can't confirm, and how the SonoHealth EKGraph fits.

The best home EKG for AFib is a single-lead monitor that lets you capture a clean 30-second trace the moment symptoms strike, stores a history you can share, and clearly flags irregular rhythms as a prompt to seek care. A device like the SonoHealth EKGraph does this, but it's important to understand the line: a home EKG can *screen for and document* possible atrial fibrillation — it cannot confirm the diagnosis, which requires a clinician.

<Warning>
  A home EKG cannot rule out a heart attack or confirm AFib on its own. For chest pain, fainting, or severe shortness of breath, **call 911**. Untreated AFib raises stroke risk, so review abnormal readings with your doctor promptly.
</Warning>

## Why is documenting AFib at home useful?

[Atrial fibrillation](/ekg/atrial-fibrillation) is often *intermittent* — it can come and go and may not show up during a short office visit. Capturing a trace during an episode gives your doctor evidence they'd otherwise miss, and because AFib meaningfully raises [stroke risk](/ekg/afib-and-stroke-risk), earlier documentation supports earlier treatment. A home device is for catching and tracking those episodes, not for self-diagnosis.

## What features matter for AFib tracking?

* **Quick, clean recording** (about 30 seconds) so you can catch a brief episode.
* **Clear rhythm classification** on the device — including a possible-AFib or arrhythmia flag.
* **A stored, shareable history** (ideally a PDF) so your cardiologist sees patterns over time.
* **Multiple recording positions** for a clearer trace — see [single-lead vs. 12-lead](/ekg/single-lead-vs-12-lead).
* **Ease of use during symptoms** — see [how to take a good reading](/ekg/how-to-take-a-good-ekg-reading).

## Can a home EKG confirm I have AFib?

No. It can flag a rhythm that *looks like* AFib and prompt you to seek care, but confirming atrial fibrillation — and distinguishing it from [atrial flutter, SVT, or benign palpitations](/ekg/heart-palpitations) — requires a clinician's interpretation, often with a clinical EKG or longer monitoring. Use the home trace as documentation you bring to that conversation.

## How the SonoHealth EKGraph fits

The [EKGraph](https://sonohealth.com/products/ekgraph-portable-ekg-monitor-detect-afib-abnormalities) records a single-lead ECG in 30 seconds and classifies each trace on its built-in screen — No Abnormalities, Arrhythmia, Bradycardia, Tachycardia, and more — then syncs to a free app for a PDF you can hand your doctor. Free unlimited storage (no subscription) makes it practical to build the dated log that AFib tracking depends on. It's FDA-cleared, FSA/HSA eligible, and backed by a 2-year warranty and 60-day trial.

## When to stop tracking and call your doctor

Persistent palpitations, a rhythm your device repeatedly flags as abnormal, fainting, or new chest symptoms all warrant medical attention rather than more home recordings — see [when to see a doctor](/ekg/when-to-see-a-doctor-heart).
