Introduction

An electrocardiogram (ECG or EKG) is a simple test that records the electrical activity of your heart.

In reality, a borderline ECG result is common and does not always point to a serious heart problem.

This article explains borderline ECG results in easy words, so you understand what they mean, what causes them, and when medical attention is needed.
