Introduction

A graphic record of the electrical activity of the heart, obtained with an electrocardiograph.

* see figure

Indications

* most arrhythmias are intermittent & not recorded on a resting ECG[6]

Contraindications

* routine screening still common in low-risk patients[7]

  • these patients underwent significantly more cardiac tests, with no evidence of benefit[7]
