Introduction:
Electrocardiogram is the first-line diagnostic imaging modality for evaluating patients with chest pain. The present study aimed to determine the capability of emergency nurses for electrocardiogram interpretation by using a more appropriate questioning method.
Methods:
This was a cross-sectional descriptive survey. A convenience sample of 96 emergency nurses was obtained from two emergency departments in Hong Kong. The electrocardiogram-interpretation capability of the emergency nurses was determined using a self-developed well-designed questionnaire comprising 10 questions on electrocardiogram interpretation. Each question carried one point, such that the maximum score was 10 points. The higher the score, the more capable was the emergency nurse at electrocardiogram interpretation.
Results:
The mean score achieved by the participants was 7.7 ± 1.8. Only 12.5% of the participants were able to answer all questions correctly. A considerable proportion of the participants were unable to recognize first-degree heart block (74.0%), second-degree heart block type I (52.1%), or third-degree heart block (39.6%). Gender, electrocardiogram training, nursing experience, and emergency department experience had significant associations with mean score.
Conclusions:
The electrocardiogram-interpretation capability of the emergency nurses was fair. Better training should be implemented to help emergency nurses recognize potentially fatal heart blocks, enabling prompt and appropriate patient treatment.

An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.

Components of the Electrocardiogram
The primary components of a normal ECG waveform in Normal sinus rhythm(NSR) include the P wave, PR interval, QRS complex, ST segment, T wave, and occasionally a U wave.
ECG waveforms are divided by vertical and horizontal lines at standard intervals.
The horizontal axis measures time and rate, and the vertical axis measures amplitude or voltage....
