A good ECG reading, also known as an electrocardiogram, is one that provides clear and accurate information about the heart's electrical activity. A normal ECG typically has the following characteristics: 1. Sinus Rhythm: The heart is beating in a regular pattern originating from the sinoatrial (SA) node, which is the heart's natural pacemaker. 2. Rate: The heart rate is between 60 - 100 beats per minute (bpm), which is considered normal for adults at rest. 3. Intervals: Important intervals such as the PR interval, QRS complex, and QT interval are within normal limits. For instance, the PR interval should be between 0.12 - 0.20 seconds, the QRS complex should last no more than 0.10 seconds, and the QT interval should be appropriate for the heart rate. 4. Waveform: The P wave, QRS complex, and T wave are present and have the correct shape and duration. 5. No Abnormalities: There are no signs of arrhythmias, conduction problems, or other abnormalities that could indicate a heart condition. read more >>

Normal ECG. A normal ECG is illustrated above. Note that the heart is beating in a regular sinus rhythm between 60 - 100 beats per minute (specifically 82 bpm). All the important intervals on this recording are within normal ranges.read more >>
