The Inconclusive Samsung ECG result is one of the most frustrating experiences when monitoring your heart health. In your frustration, you might be wondering, "What does Inconclusive mean on my Samsung ECG?" Or you might be thinking, "Why does my Samsung ECG keep saying Inconclusive?" In this guide, we'll help answer these questions, and we'll share some tips on how to take ECGs that don't result in Inconclusive. Let's dive in.

What Does Inconclusive Mean on My Samsung ECG?

If you're getting Inconclusive ECGs, it could be due to any of the following reasons:

  • The way you're taking your ECG is leading to a low signal quality.
  • You have a low heart rate or high heart rate, which Samsung classifies as Inconclusive.
  • Your heart rate is above 120 beats-per-minute (bpm) and you're showing signs of Afib.
  • You have a pacemaker or implantable cardioverter defibrillator (ICD).
  • You're showing signs of other arrhythmias or heart conditions outside of Sinus Rhythm and Atrial Fibrillation that the Samsung ECG app isn't designed to recognize.

Other arrhythmias that might cause an Inconclusive ECG on your Samsung Watch include Premature Atrial Contraction (PAC), Premature Ventricular Contraction (PVC), Supraventricular Tachycardia (SVT), and Ventricular Tachycardia (V-Tach).

So How Do I Avoid an Inconclusive ECG?

First things first, let's make sure you're taking an ECG that your Samsung Watch views as a good ECG reading.

To do this, see if you're still getting an Inconclusive ECG after each of the following steps:

  • Get comfortable and relax. If you take your ECG when your arms are shaking or moving, it can lead to an Inconclusive ECG. Sit down. Take three, long, deep breaths. Place your arms flat on a table or flat in your lap in order to minimize movement.
  • Make sure your Samsung Watch fits snuggly. Your ECG's signal quality is low when your Samsung Watch is so loose that it doesn't touch your skin. Fasten your Samsung Watch so that it's both snug on your wrist, and so that the back of the watch is touching your skin.
  • Keep your wrist and Samsung Watch clean and dry. Your sweat can interfere with the signal quality of your ECG. First, take off your Samsung Watch. Then, dry the area where you normally wear your Samsung Watch (for most people, this is your wrist, but for the curious or adventurous this could be your chest or ankle). Next, dry the finger you use to place on the side of the Samsung Watch to start your ECG. Last, dry your watch sides and the back of your watch to clean all of the sensors involved in taking your ECG. You're now ready to strap your Samsung Watch back on and take another ECG.
  • Check your wrist orientation setting. If you take your ECG on the "wrong" wrist, it can confuse your Samsung Watch. On your Samsung Watch, go to Settings > General > Orientation. See which wrist you've selected in the Orientation setting. Then, confirm that your Samsung Watch is strapped onto that same wrist of yours.
  • Distance yourself from other electronics. If you have electronic devices nearby that are plugged into an outlet, it can cause electrical interference with your ECG. If you can, try moving away from any electronic devices that are plugged into an outlet.

if you're still seeing Inconclusive ECGs, it may be due to a low heart rate on your Samsung ECG or a high heart rate on your Samsung ECG. As always, if you're experiencing symptoms, or if you see signs of abnormal heart rhythms, contact your healthcare provider as soon as possible to rule out underlying heart conditions. Qaly's ECG how to read guide is also a great next step for clarity on irregular heartbeats.
